The wings of Lepidoptera are minutely scaled, which gives the name to this order; the name Lepidoptera was coined in 1735 by Carl Linnaeus for the group of "insects with four scaly wings". It is derived from Ancient Greek lepis (λεπίς) meaning "(fish) scale" (and related to lepein "to peel") and pteron (πτερόν) meaning "wing".
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly.They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.
The wings on the metathorax are transformed into the halteres or rocker arms. From this characteristic comes the name of the order, from the Greek dipteros , which means "two wings". In consequence of this morphological structure, the mesothorax represents the segment of greater development and complexity, while the prothorax and metathorax are ...
Because the mesothorax and metathorax hold the wings, they have a combined name called the pterothorax (pteron = wing). The forewing, which goes by different names in different orders (e.g., the tegmina in Orthoptera and elytra in Coleoptera), arises between the mesonotum and the mesopleuron, and the hindwing articulates between the metanotum ...
A notable example are the Lepidoptera, the insect order comprising moths and butterflies, which have scales on their wings and on the head, parts of the thorax and abdomen, and parts of the genitalia.
The mesothorax is the middle of the three segments of the thorax of hexapods, and bears the second pair of legs. Its principal sclerites (exoskeletal plates) are the mesonotum ( dorsal ), the mesosternum ( ventral ), and the mesopleuron ( lateral ) on each side.
mesothorax the middle segment of the thorax, between the prothorax and the metathorax. metalmarks small metallic-looking spots commonly found on the wings of Riodinidae. metathorax The third and last segment of the thorax after the mesothorax. micropterous Having short elytra, shorter than the abdomen. mixomycetophagy feeding on myxomycetes ...
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
