Anthia sexguttata, referred to commonly as the six-spot ground beetle, is a beetle of the Family Carabidae.
Adults measure approximately 4 cm (1.5 inches), are black with six relatively large, white, dorsal spots (four over the elytra and two on the thorax). Other patterns are possible although the pattern is always symmetrical.
The larva has a flattened form, a large head capsule, and prominent mandibles. [1]
The species occurs in the drier parts of South Asia. It is found in a variety of habitats including natural forests and dry scrubland. The species was found in a variety of human-modified habitats including agriculture fields and urban parks. [2]
Adult A. sexguttata feed on other insects and snails. [3] They are also predators on defoliating pests of Tectona grandis , such as Pyrausta machaeralis and Hyblaea puera . [4] It is also an important predator on beetle pests of sugarcane crops. [5]
A. sexguttata are well known predators of a number of pests of commercially important trees including Tectona grandis . [4]
The compound eyes of A. sexguttata exhibit sensitivity changes in a clear circadian rhythm, with both eyes being coupled when in total darkness. [6]
The mite Regenpolipus madrasensis is described from A. sexguttata. [7]
Beetles are insects that form the order Coleoptera, in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Some others also have unusual characteristics, such as fireflies, which use a light-emitting organ for mating and communication purposes.
Teak is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. Tectona grandis has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs. The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and various small projects.
Ground beetles are a large, cosmopolitan family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are herbivorous or omnivorous.
Harpalinae is the largest subfamily of ground beetles, containing more than 19,000 species worldwide.
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae.
Histeridae is a family of beetles commonly known as clown beetles or hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other hister beetles, they must be isolated when collected.
Anthia is a genus of the ground beetle family (Carabidae) from Africa and Asia. Species of Anthia can spray a jet of formic acid up to 30 centimetres (12 in), which, if not treated, can cause blindness in animals that harass the beetles.
Hyblaea puera, the teak defoliator, is a moth and cryptic species complex native to South Asia and South-east Asia. It was first described by Pieter Cramer in 1777. The species has also been recently reported to be present in Central America and Africa. The caterpillar feeds on teak and other trees. It is considered to be one of the major teak pests around the world.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad.
The Brachypsectridae are a family of beetles commonly known as the Texas beetles. There are only two extant genera, Brachypsectra and Asiopsectra. Brachypsectra has a cosmopolitan distribution, mostly in arid regions, while Asiopsectra is found in Central Asia and the Middle East.
Epomis is a subgenus of ground beetle genus Chlaenius. The larvae of this subgenus are notable for being obligate role-reversal predators. Amphibians such as frogs are normally predators of beetles; however, Epomis larvae feed exclusively on amphibians.
Anthia sexmaculata, common name Egyptian predator beetle, is a species of beetles of the family Carabidae.
A stemborer is any insect larva, or arthropod, that bores into plant stems. However the term most frequently refers among the Coleoptera to the larva of certain longhorn beetles such as Dorysthenes buqueti and those of the genus Oberea, and among the Lepidoptera to certain moths of the Crambidae, Castniidae, Gelechiidae, Nolidae, and Pyralidae families.
Anisodactylus binotatus is a species of ground beetle native to Europe. It was discovered as being introduced to Canterbury, New Zealand in 1938. Anisodactylus binotatus is a species of Carabidae, also known as the ground beetle family. Although this species of beetle has no official recorded common names, literature from England refers to it as the common shortspur beetle.
Hypomeces pulviger, also known as the gold-dust weevil or green weevil, is a species of beetle in the true weevil family. The adult weevil can reach a length of about 14 mm (0.6 in) and is covered with iridescent green or yellowish-green dust-like scales all over the body. This species can be found in India, tropical Southeast Asia, and the Philippines. Both the larvae and adults are crop pests. The larvae live in and pupate in the soil, feeding on living plant roots. The adult weevils are long-lived, doing damage to foliage, and sometimes defoliating young bushes and nursery trees.
The Calleida viridipennis is a species of ground beetle belonging to the Carabidae family, and are referred to as carabid beetles. It is found in various states, including New York, New Mexico, Louisiana, and Florida. Habitat preferences include forests and swamps. C. virdipennis is a particular carabid beetle that is, on average, 10 mm long. Recognizable by a green-black metallic exoskeleton, it has a trapezoidal head shape. Its large eyes are also characteristic of the species. Below the exoskeleton reside functional wings, giving the beetle flight capacity.
Rhynocoris marginatus is a species of assassin bug in the family Reduviidae. It is a predator of other insects and is found in Asia. Crops in India on which it has been found feeding on pests include sugarcane, pigeon pea, cardamom, cotton, tea, and peanuts. The insects are potentially useful in biological control because they are more resistant to pesticides than are the pests on which they feed.
Gelonaetha hirta, commonly known as Hibiscus Long-horned beetle, or Long horn teak borer, is a species of longhorn beetle. It is distributed in Sri Lanka, India, Myanmar, Thailand, Laos, Hainan Island, Taiwan, Borneo, Philippines, Micronesia, Polynesia and West Indies.
Gonocephalum depressum is a species of darkling beetle. The species is widespread in South Asian and South East Asian countries such as, India, Bhutan, Nepal, Pakistan, Indonesia, Laos, Philippines, Sri Lanka, Myanmar, Taiwan, Afghanistan and China.
Schizonycha ruficollis, is a species of dung beetle found in India and Sri Lanka.
