The insect order Lepidoptera consists of moths and butterflies (43 superfamilies). [1] Most moths are night-flying, while the butterflies (superfamily Papilionoidea ) are the mainly day-flying. Within Lepidoptera as a whole, the groups listed below before Glossata contain a few basal families accounting for less than 200 species; the bulk of ...
Articles relating to insects, pancrustacean hexapod invertebrates of the class Insecta.They are the largest group within the arthropod phylum.Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae.
In contrast, a large majority of the insect species of the tropics and the southern hemisphere are probably undescribed. [11] Some 30–40,000 species inhabit freshwater; very few insects, perhaps a hundred species, are marine. [12] Insects such as snow scorpionflies flourish in cold habitats including the Arctic and at high altitude. [13]
In many insect species, the forewing and hindwing are coupled together, which improves the aerodynamic efficiency of flight. The most common coupling mechanism (e.g., Hymenoptera and Trichoptera) is a row of small hooks on the forward margin of the hindwing, or "hamuli", which lock onto the forewing, keeping them held together (hamulate coupling).
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information.
