ZoologyTrichoptera are small moth-like insects with two pairs of hairy membranous wings. They have aquatic larvae and terrestrial adults
Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food.
Annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them.
TaxonomyThey are closely related to the
Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera.
