__NOTOC__ The Adelidae or fairy longhorn moths are a family of monotrysian moths in the lepidopteran infraorder Heteroneura. Most species have at least partially metallic patterns coloration and are diurnal, sometimes swarming around the tips of branches with an undulating flight. Others are crepuscular and have a drab coloration. Fairy longhorn moths have a wingspan of 4-28 millimeters, and males often have especially long antennae, 1-3 times as long as the forewing. They are widespread across the world and can be found over much of North America and Eurasia from April to June. About 50 species occur in Europe, of which most widely noted is the Green Longhorn (''Adela reaumurella'') which can sometimes reach great abundance; due to climate change〔Kuchlein & Ellis (2004)〕 its peak flying season is shifting towards spring. In general, they are more plentiful in the Northern Hemisphere, but the family occurs in the Neotropics, sub-Saharan Africa, South-East Asia and Australia too.〔Edwards (2007), FE (2009)〕 Adelidae are usually closely restricted to particular hostplants (), in which the females insert their eggs or just lay among leaf litter, and the caterpillars make a case, completing their development on the ground. Fairy longhorn moths feed in sunshine on nectar from the flowers of herbaceous (woody) plants. ==Systematics== Fairy longhorn moths belong to the superfamily Incurvarioidea, one of the basal ("monotrysian") branches of the advanced moth infraorder Heteroneura. By Lepidopteran standards, they are thus still rather primitive micromoths. But like other Heteroneura, they already possess the apomorphic sucking proboscis – usually considered a defining feature of Lepidoptera, but actually the most ancestral moths still live on solid food which they chew.〔Davis (1999)〕 The Adelidae were previously placed as the subfamily Adelinae within the family Incurvariidae. ===Subfamilies=== The Adelidae are usually divided into 2 subfamilies, but most genera are actually of uncertain or basal relationships. Selected species are also listed:〔Wikispecies (2008-OCT-31), FE (2009), and see references in Savela (2003)〕 Subfamily Adelinae * ''Adela'' Latreille, 1796 * * ''Adela croesella'' * * ''Adela reaumurella'' – Green Longhorn * ''Cauchas'' Zeller, 1839 * * ''Cauchas rufimitrella'' * ''Nemophora'' Illiger & Hoffmannsegg, 1798 (tentatively placed here) * * ''Nemophora degeerella'' – Longhorn Moth * * ''Nemophora metallica'' * * ''Nemophora ochsenheimerella'' Subfamily Nematopogoninae * ''Ceromitia'' Zeller, 1852 (tentatively placed here) * * ''Ceromitia iolampra'' * ''Nematopogon'' ''Incertae sedis'' * ''Subclemensia'' * ''Trichofrons'' The genus ''Tridentaforma'' is sometimes placed among the Adelidae ''incertae sedis'' too; others assign it to the closely related Prodoxidae.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Adelidae」の詳細全文を読む スポンサード リンク
