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; [2] new species are discovered frequently, with estimates suggesting ...
This article classifies the subgroups of the order Coleoptera down to the level of families, following the system in "Family-group names in Coleoptera (Insecta)", Bouchard, et al. (2011), [1] with corrections and additions from 2020, [2] with common names from bugguide.net.
The Carboniferous insect species Stephanastus polinae has been interpreted by some authors as the sister group of Coleoptera and Strepsiptera (as its own extinct order, Skleroptera), but this interpretation has been disputed and it has been alternatively suggested to be a member of the extinct order Protelytroptera (a stem group of the modern ...
The most diverse insect orders are the Hemiptera (true bugs), Lepidoptera (butterflies and moths), Diptera (true flies), Hymenoptera (wasps, ants, and bees), and Coleoptera (beetles), each with more than 100,000 described species.
Of the 24 identified orders of insects, five dominate in terms of numbers of described species, namely Coleoptera (beetles), Lepidoptera (butterflies and moths), Diptera (flies and mosquitoes), Hymenoptera (ants, bees, wasps and sawflies) and Hemiptera (true bugs, e.g. cicadas, aphids, leafhoppers, bed bugs and assassin bugs).
The elytra of this cockchafer beetle are readily distinguished from the transparent hindwings.. An elytron (/ ˈ ɛ l ɪ t r ɒ n /; from Ancient Greek ἔλυτρον (élutron) 'sheath, cover'; pl.: elytra, / ˈ ɛ l ɪ t r ə /) [1] [2] is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs such as the family Schizopteridae are extremely similar; in true ...
Coleopterology (from Coleoptera and Greek-λογία, -logia) is the scientific study of beetles, a branch of entomology. Practitioners are termed coleopterists and form groups of amateurs and professionals for business and pleasure. Among these is The Coleopterists Society, an international organization based in the United States.
Polyphaga is the largest and most diverse suborder of beetles.It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species discovered thus far.
