Amphiesmenoptera
Sign in to saveAmphiesmenoptera is an insect superorder, established by S. G. Kiriakoff, but often credited to Willi Hennig in his revision of insect taxonomy for two sister orders: Lepidoptera (butterflies and moths) and Trichoptera (caddisflies). In 2017, a third fossil order was added to the group, the Tarachoptera.
Species
類脈總目是由威利·亨尼希所建立的，其下有毛翅目和鱗翅目兩個目。2017年，第三個化石目Tarachoptera被加上該組。 毛翅目和鱗翅目有許多的相同裔徵（共同衍徵），這證明了牠們有著相同的祖先： 雄性有一條性染色體，雌性有兩條； 翅膀上有濃密的棘毛（在鱗翅目裡演化為鱗）； 前翅有獨特的翅脈圖案（雙環臀脈）； 幼蟲的嘴巴構造和唾腺可以生成和控制絲。 因此，這兩個目被歸在類脈總目。這個總目可能是在侏羅紀時演化出來的，由已經滅絕了的Necrotaulidae。鱗翅目和毛翅目有些許不同的特徵，包括翅脈、翅膀上的鱗、沒有尾鬚、沒有單眼，以及腳部上的變化。

Amphiesmenoptera is an insect superorder, established by S. G. Kiriakoff, but often credited to Willi Hennig in his revision of insect taxonomy for two sister orders: Lepidoptera (butterflies and moths) and Trichoptera (caddisflies). In 2017, a third fossil order was added to the group, the Tarachoptera.
Trichoptera and Lepidoptera share a number of derived characters (synapomorphies) which demonstrate their common descent: Females, rather than males, are heterogametic (i.e. their sex chromosomes differ). Dense setae are present in the wings (modified into scales in Lepidoptera). There is a particular venation pattern on the forewings (the double-looped anal veins). Larvae have mouth structures and glands to make and manipulate silk.
