Holcaspis Angustula
''Holcaspis'' is a genus of beetles in the family Carabidae, endemic to New Zealand. Taxonomy The genus was originally proposed by Maximilien Chaudoir, Chaudoir in 1865, with a large number of species added by Thomas Broun in the late 19th century and early 20th century. The genus was revised by Everard Britton in 1940, and most recently by Michael Butcher in 1984, with several species added by Peter Johns (entomologist), Peter Johns in 2003. A phylogenetic analysis by Hanboonsong generally agreed with Butcher's species list, but found that ''H. oedicnema'' displayed an unusual amount of genetic variation and is probably a species complex. Description ''Holcaspis'' beetles are black ground beetles, ranging between 10–26 mm in length. The Insect mouthparts#Labium, mentum has deep pits on either side, and the Labrum (arthropod mouthpart), labrum has six Seta, setae. The head has a variable H-shaped impression between the eyes. All species are flightless, with fused Elytron, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. 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 life-forms; 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 (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
