What kind of insect is this, and is this venomous, or dangerous? Don't need full species name just common name will do, color is red. Grandma always warned me of this, they usually are seen in monsoon season during heavy rains. They coil upwhen disturb . Location: Country: India, lower himalayas Google Map :Exact location A miniature version of this also exist in my area don't have pic though.

Given the shape and the number of legs. That most definitely is not an insect. An insect has exactly 6 legs. No more, no less.

That critter in your picture is some kind of millipede (“a thousand feet”; not literally a thousand, of course;, not to be confused with a centipede (“a hundred feet”; also not literally a hundred).

Millepedes are mostly harmless to humans. They eat things like dead plant matter or fungi. They sometimes also eat seedlings so they can be considered pests in gardens.

And given the colour, that's possibly a rusty millipede ( They have a very wide distribution around the Indo-Malayan region. Although there seems to be no recorded observation of it on iNaturalist around your region (

Crawling Pests Tips

Bed bugs are the bane of any home or business, and it’s important you get any infestation identified and dealt with quickly. These small creatures quickly make sleeping and resting a nightmare, and their itchy bites can be a huge distraction.

Although bed bugs will likely be around for millennia, there’s no reason why you have to give them free accommodation.

What Are Bed Bugs?

Bed bugs are little insects that feed on blood. To do that, they must feed on people while they’re sleeping, which is why they’re associated with bedding. They likely started feeding on animals with nests or permanent resting places, such as bats and birds, but they quickly discovered a liking for human blood. Typically, they can range from 1/16 of an inch to 3/16 of an inch, and because they’re oval and brownish, they may initially look a little bit like an apple seed.

Bed bugs don’t spread disease, but they are unpleasant due to the itchy bites. They can survive for up to a year without feeding.

Crawling Insects

Who loves crawling insects? While there are many who will happily keep some as pets, very few people want them crawling around in their homes. So what do you do if you think you have some sort of infestation? The key is species identification.

Types of Crawling Insect Species

While not all of these are technically insects, they are all unwanted, so we’ve broken it down for you.


These include spiders, ticks and scorpions. Arachnids have eight legs (barring accidents) but they do not have antennae. Scorpions can be identified by their tail and pincers, technically called “grasping pedipalps,” whereas spiders lack these features. Spiders lay eggs, while scorpions generally give birth to live young.

Termites and ants

Although these two groups look similar, they are actually unrelated. Termites are members of the cockroach family, whereas ants are closely related to wasps and bees. You can tell the difference by looking at their waists. Termites have a thick waist and are white, and their antennae are straight. Ants come in a huge range of colors, their antennae are bent, and they have highly defined waists that taper down to almost nothing. A termite infestation is an immediate problem that needs to be dealt with. An ant problem is an annoyance, but they won’t generally cause major damage.

Fleas and lice

These are an example of convergent evolution, where two relatively unrelated species develop similar techniques for survival. Fleas are closely related to flies (they are wingless flies), whereas lice have their own subsection of Insecta. Both live on animals (and sometimes humans), but fleas require the host to have a set place to sleep (as part of the life cycle occurs in the bedding), whereas lice stay on the host.

Millipedes and centipedes

These are both members of Myriapoda (literally, many legs — scientists aren’t always very imaginative), and they are more closely related to crabs than they are insects. You can identify them by their many legs — the minimum they will have is 10, and the maximum is around 750. Centipedes have one pair of legs per segment millipedes have two pairs of legs per segment.


There are hundreds of cockroach species, but four are particularly well-known as pests. They have broad, flattened bodies and a tough exoskeleton, and their antennae are flexible. They inhabit dark areas.

Insect Identification

To identify insects, you must look at the number of legs and body parts they have. For example, all insects are identified by the fact they have three pairs of legs and three body parts—a head, thorax, and abdomen. Another feature that identifies insects is their two compound eyes.

Insects are also classified as invertebrates. This means that they have soft bodies without bones. Some creeping green insects like beetles and grasshoppers have an exoskeleton—a hard protective shell. Other flying insects such as aphids and butterflies have soft bodies.

Many adult insects also have wings, even though not all winged insects fly.

Caterpillars are an interesting example of crawling larval insects. Like all insect types, caterpillars have six proper legs—although they seem to have more, called prolegs. After metamorphosis, caterpillars change into flying winged insects with stunning wing patterns.

Mystery of the Disappearing Bugs

These ancient giant insects fascinate Jon Harrison. A physiologist and professor of biology at Arizona State University. Harrison wants to know why giant insects evolved, and why they disappeared. The answer may lie in how insects breathe. Harrison and his laboratory are busy studying how the breathing of modern insects affects their body size. They are finding that, because of the way insects are built, higher oxygen levels usually means bigger insects!


Understanding the basic parts of an insect or spider will help you in identifying the bug in question.

First off, knowing the differences between insects and other insect-like creatures is helpful. Insects have three body segments and six legs. Insects may also have wings, antennae, and mandibles.

Other insect-like creatures, including spiders, centipedes, millipedes, ticks, mites, and scorpions, may also show up in your yard or inside your house. These creatures have eight or more legs and varying numbers of body segments.

By understanding these bug parts, you can better communicate what you are seeing to aid in identification. Likewise, you&rsquoll better understand what the experts are saying as they assist you.

The insect parts you should know are:

HEAD &ndash This section of an insect contains eyes, mouth components and, in some species, antennae.

THORAX &ndash This area, immediately behind the head and neck, hosts the insect&rsquos legs and wings.

ABDOMEN &ndash This portion contains the insect&rsquos digestive tract, reproductive organs and, in some species, a stinger.

The arachnid (spiders, mites, ticks) parts you should know are:

CEPHALOTHORAX &ndash A fusion of the head and a thorax, this section also contains the legs of the spider, scorpion, mite or tick. OPISTHOSOMA (abdomen) &ndash This area contains the respiratory organs, heart, digestive tract, reproductive organs and, in some species, the web-spinning parts.

The myriapod (centipedes, millipedes) parts you should know are:

HEAD &ndash This portion of the myriapod includes primitive eyes, antennae, and mouthparts.

TRUNK &ndash This section features multiple body segments which provide extreme flexibility, many pairs of legs (often ten or more) and nearly all of the creature&rsquos internal organs.

Crawling Insect Library

Although we may turn up our noses in disgust when we see one of these insects crawling across our basement or kitchen floors, we can learn how to control them so they don't control us! Using a product that features diatomaceous earth such as Safer® Brand Ant and Crawling Insect Killer Powder allows you to eliminate crawling insects such as ants, ticks, stink bugs, roaches, silverfish, earwigs and bed bugs without using harmful chemicals.

By learning more about these insects as well as finding solutions to eliminate them, you can feel relieved knowing your home or organic garden is free from crawling insects.

The ant's remarkable antennae can sense changes in air pressure, perceive odors, and feel movement and vibrations. Its body is made up of three segments which are surrounded by an exoskeleton.


The name coccinellids is derived from the Latin word coccineus meaning "scarlet". [7] The name "ladybird" originated in Britain where the insects became known as "Our Lady's bird" or the Lady beetle. [8] [9] Mary (Our Lady) was often depicted wearing a red cloak in early paintings, and the spots of the seven-spot ladybird (the most common in Europe) were said to symbolise her seven joys and seven sorrows. [8] [10] In the United States, the name was adapted to "ladybug". Common names in some other European languages have the same association for example, the German name Marienkäfer translates to Marybeetle. [11]

Coccinellids are often conspicuously coloured yellow, orange, or red with small black spots on their wing covers, with black legs, heads and antennae. There is, however, great variation in these colour patterns. For example, a minority of species, such as Vibidia duodecimguttata, a twelve-spotted species, have whitish spots on a brown background. Coccinellids are found worldwide, with over 6,000 species described. [12] [13]

Most coccinellids have round to elliptical, dome-shaped bodies with six short legs. Depending on the species, they can have spots, stripes, or no markings at all. Seven-spotted coccinellids are red or orange with three spots on each side and one in the middle they have a black head with white patches on each side.

As well as the usual yellow and deep red colourings, many coccinellid species are mostly, or entirely, black, dark grey, gray, or brown, and may be difficult for non-entomologists to recognise as coccinellids at all. Conversely, non-entomologists might easily mistake many other small beetles for coccinellids. For example, the tortoise beetles, like the ladybird beetles, look similar because they are shaped so that they can cling to a flat surface so closely that ants and many other enemies cannot grip them. [ citation needed ]

Non-entomologists are prone to misidentify a wide variety of beetle species in other families as "ladybirds", i.e. coccinellids. Beetles are particularly prone to such misidentification if they are spotted in red, orange or yellow and black. Examples include the much larger scarabaeid grapevine beetles and spotted species of the Chrysomelidae, Melyridae and others. Conversely, laymen may fail to identify unmarked species of Coccinellidae as "ladybirds". Other beetles that have a defensive hemispherical shape, like that of the Coccinellidae (for example the Cassidinae), also are often taken for ladybirds. [ citation needed ]

A common error, totally unfounded, is that the number of spots on the insect's back indicates its age. [14] [15] In fact, the underlying pattern and colouration are determined by the species and genetics of the beetle, and develop as the insect matures. In some species its appearance is fixed by the time it emerges from its pupa, though in most it may take some days for the colour of the adult beetle to mature and stabilise. Generally, the mature colour tends to be fuller and darker than the colour of the callow. [ citation needed ]

Coccinellids are best known as predators of Sternorrhyncha such as aphids and scale insects, but the range of prey species that various Coccinellidae may attack is much wider. A genus of small black ladybirds, Stethorus, presents one example of predation on non-Sternorrhyncha they specialise in mites as prey, notably Tetranychus spider mites. Stethorus species accordingly are important in certain examples of biological control. [16] They are natural predators of a range of serious pests, such as the European corn borer, a moth that costs US agriculture industry more than $1 billion annually in crop losses and population control. [17] [18]

Various larger species of Coccinellidae attack caterpillars and other beetle larvae. [16] Several genera feed on various insects or their eggs for example, Coleomegilla species are significant predators of the eggs and larvae of moths such as species of Spodoptera and the Plutellidae. [19] Larvae and eggs of ladybirds, either their own or of other species, can also be an important food resource when alternative prey are scarce. As a family, the Coccinellidae used to be regarded as purely carnivorous, [20] but they are now known to be far more omnivorous than previously thought, both as a family and in individual species examination of gut contents of apparently specialist predators commonly yield residues of pollen and other plant materials. Besides the prey they favour, most predatory coccinellids include other items in their diets, including honeydew, pollen, plant sap, nectar, and various fungi. The significance of such nonprey items in their diets is still under investigation and discussion. [21]

Apart from the generalist aphid and scale predators and incidental substances of botanical origin, many Coccinellidae do favour or even specialise in certain prey types. This makes some of them particularly valuable as agents in biological control programmes. Determination of specialisation need not be a trivial matter, though for example the larva of the Vedalia ladybird Rodolia cardinalis is a specialist predator on a few species of Monophlebidae, in particular Icerya purchasi, which is the most notorious of the cottony cushion scale species. However, the adult R. cardinalis can subsist for some months on a wider range of insects plus some nectar. [22]

Certain species of coccinellids are thought to lay extra infertile eggs with the fertile eggs, apparently to provide a backup food source for the larvae when they hatch. The ratio of infertile to fertile eggs increases with scarcity of food at the time of egg laying. Such a strategy amounts to the production of trophic eggs. [23]

Some species in the subfamily Epilachninae are herbivores, and can be very destructive agricultural pests (e.g., the Mexican bean beetle). Again, in the subfamily Coccinellinae, members of the tribe Halyziini and the genus Tythaspis are mycophagous.

While predatory species are often used as biological control agents, introduced species of coccinellids are not necessarily benign. Species such as Harmonia axyridis or Coccinella septempunctata in North America outcompete and displace native coccinellids and become pests themselves. [24]

The main predators of coccinellids are usually birds, but they are also the prey of frogs, wasps, spiders, and dragonflies. The bright colours of many coccinellids discourage some potential predators from making a meal of them. This phenomenon, called aposematism, works because predators learn by experience to associate certain prey phenotypes with a bad taste. A further defence, known as "reflex bleeding", exists in which an alkaloid toxin is exuded through the joints of the exoskeleton, triggered by mechanical stimulation (such as by predator attack) in both larval and adult beetles, deterring feeding.

Coccinellids in temperate regions enter diapause during the winter, so they often are among the first insects to appear in the spring. Some species (e.g., Hippodamia convergens) gather into groups and move to higher elevations, such as a mountain, to enter diapause.

Most coccinellids overwinter as adults, aggregating on the south sides of large objects such as trees or houses during the winter months, dispersing in response to increasing day length in the spring. [25]

Predatory coccinellids are usually found on plants which harbour their prey. They lay their eggs near their prey, to increase the likelihood the larvae will find the prey easily. In Harmonia axyridis, eggs hatch in three to four days from clutches numbering from a few to several dozen. Depending on resource availability, the larvae pass through four instars over 10–14 days, after which pupation occurs. After a teneral period of several days, the adults become reproductively active and are able to reproduce again later, although they may become reproductively quiescent if eclosing late in the season. Total life span is one to two years on average. [26]

Population shift in Great Britain and Ireland

The atlas Ladybirds (Coccinellidae) of Britain and Ireland published in 2011 [27] showed a decline of more than 20% in native species due to environmental changes and competition from foreign invaders. The distribution maps, compiled over a 20-year period with help from thousands of volunteers, showed a decline in the numbers of the common 10-spot and 14-spot ladybirds and a number of other species, including the 11-spot, 22-spot, cream-spot, water and hieroglyphic ladybirds, Coccidula rufa, Rhyzobius litura and Nephus redtenbacheri. Conversely, increases were seen in the numbers of harlequin, orange, pine, and 24-spot ladybirds, as well as Rhyzobius chrysomeloides. The kidney spot ladybird was recorded in Scotland for the first time in recent years, and the 13-spot was found to have recolonised Cornwall, Devon, and the New Forest. The most commonly recorded species was the 7-spot, closely followed by the Asian harlequin — an invader that arrived from continental Europe in 2003 after being introduced to control pests. An 'explosion' in the number of orange ladybirds, which feed on mildew, is thought to have been due to the warmer, damper conditions that now prevail in parts of England. [28]


In North America, coccinellids usually begin to appear indoors in the autumn when they leave their summer feeding sites in fields, forests, and yards and search out places to spend the winter. Typically, when temperatures warm to the mid-60s °F (around 18 °C) in the late afternoon, following a period of cooler weather, they will swarm onto or into buildings illuminated by the sun. Swarms of coccinellids fly to buildings in September through November depending on location and weather conditions. Homes or other buildings near fields or woods are particularly prone to infestation. [29]

After an abnormally long period of hot, dry weather in the summer of 1976 in the UK, a marked increase in the aphid population was followed by a "plague" of ladybirds, with many reports of people being bitten as the supply of aphids dwindled. [30] [31]

The presence of coccinellids in grape harvests can cause ladybird taint in wines produced from the grapes. [32]

As an invasive species

Harmonia axyridis (the harlequin ladybird) was introduced into North America from Asia in 1979 to control aphids, but it is now the most common species, outcompeting many of the native species. [33] It has since spread to much of western Europe, reaching the UK in 2004. [33] [34] It has become something of a domestic and agricultural pest in some regions, and gives cause for ecological concern. It has similarly arrived in parts of Africa, where it has proved variously unwelcome, perhaps most prominently in vine-related crops. [35]

In culture

Ladybirds have long been of interest to children. They had many regional names (now mostly disused) in English, such as variations on Bishop-Barnaby (Norfolk and Suffolk dialect) – Barnabee, Burnabee, the Bishop-that-burneth, and bishy bishy barnabee. [36] [37] The etymology is unclear, but it may be from St. Barnabas' feast in June, when the insect appears, or a corruption of "Bishop-that-burneth", from the fiery elytra of the beetles. [38]

The ladybird was immortalised in the popular children's nursery rhyme Ladybird Ladybird:

Ladybird, ladybird, fly away home
Your house is on fire and your children are gone
All except one, and that's Little Anne
For she has crept under the warming pan.

This poem has its counterpart in German as Marienwürmchen, collected in Des Knaben Wunderhorn, and set to music by Robert Schumann as Op. 79, No. 13, and a Polish nursery rhyme, "Little Ladybirds' Anthem", of which a part ("fly to the sky, little ladybird, bring me a piece of bread") became a saying. [39]

Many cultures consider ladybirds lucky and have nursery rhymes or local names for the insects that reflect this. For instance, the Turkish name for the insect is uğur böceği, literally meaning 'good luck bug'. In many countries, including Russia, Turkey, and Italy, the sight of a coccinellid is either a call to make a wish or a sign that a wish will soon be granted.

In Christian areas, they are often associated with the Virgin Mary, and the name that the insect bears in the various languages of Europe corresponds to this. Although historically many European languages referenced Freyja, the fertility goddess of Norse mythology, in the names, the Virgin Mary has now largely supplanted her, so that, for example, freyjuhœna (Old Norse) and Frouehenge have been changed into marihøne (Norwegian) and Marienkäfer (German), which corresponds with Our Lady's bird. [40] Sometimes, the insect is referred to as belonging directly to God (Irish bóín Dé, Polish boża krówka, Russian божья коровка [bozhya korovka], all meaning 'God's [little] cow'). [41] In Dutch it is called lieveheersbeestje, meaning 'little animal of our Good Lord'. In both Hebrew and Yiddish, it is called "Moshe Rabbenu's (i.e., Moses's) little cow" or "little horse", apparently an adaptation from Slavic languages. Occasionally, it is called "little Messiah". [42]

The insects have been used to symbolise Ladybird Books (part of Penguin Group), [43] [44] and the Ladybird range of children's clothing sold by the former high street chain Woolworth's in the UK, [45] while the ladybird street tile is a symbol against senseless violence in the Netherlands, and is often placed on the sites of deadly crimes. [46] They have also been adopted as the mascot of Candanchú, [47] a ski resort near Canfranc in the Spanish Pyrenees. The ladybird also serves as a long-standing symbol for the Swedish People's Party of Finland. [48] Ladybirds have served as the US state insects of Delaware, Massachusetts, New Hampshire, New York, Ohio, and Tennessee, though only New York has selected a species native to the United States (Coccinella novemnotata) the other states have all adopted an invasive European species (Coccinella septempunctata). [49]

Insect crawling Identification - Biology

The stinging Hymenoptera are taxonomically divided into three principal groups: ants, bees, and wasps. The majority of allergic reactions to stings are due to this order of insects. This topic reviews the biology and identification of the flying Hymenoptera that include bees, yellow jackets, hornets, and wasps. Avoidance of the flying Hymenoptera is discussed separately, as are fire ants, which are also members of the Hymenoptera order. (See "Stinging insects: Avoidance" and "Entomology and control of imported fire ants".)

Numerous misconceptions about Hymenoptera taxonomy, biology, stinging behavior, and sting avoidance are widespread throughout the clinical literature [1]. This is due partly to the repeated citation of references written by nonentomologists containing fundamental errors and partly to the extensive use of common names for these insects, such as "bee," "wasp," and "hornet." These informal expressions are often used imprecisely by clinicians, as well as the general public. However, biologists have long adhered to a set of specific meanings for the most frequently used insect common names, as well as a standardized peer review process to create new ones [2,3]. These familiar terms, when used correctly, can facilitate communication between clinicians and their patients.

This topic review will adhere to the well-established entomologic convention that calls the aculeus (ie, a modified ovipositor used as a venom-injection device) a "sting," although the colloquial term is "stinger" [4-6]. No male Hymenoptera can sting because the aculeus is a female organ.

The stinging Hymenoptera are taxonomically divided into three principal groups: ants, bees, and wasps. Only bees and wasps will be discussed here.

Insect Classification – The Characteristics Of Insects

Insects are found in many different environments. They come in many shapes, sizes, and colors. However, all insects share several defining characteristics that set them apart from other animals. All insects have:

  • 3 pair of legs
  • an exoskeleton
  • usually have wings at some stage in life
  • antennae
  • 3 body segments: head, thorax, and abdomen
  • life cycle involves metamorphosis (either complete or incomplete)
