Larva mesonotum either membranous or with pair of small, curved plates; claws of hind and middle legs are equal in length; antennae at least 8 times longer than wide. Larval case of some species a "log cabin" type made from twigs; in some other species, the case is made from leaf and stem sections. [adapted from "How to Know the Insects". Roger Bland. 1978.]
