Family Ypsolophidae
Three genera in North America: about 50 species of Ypsolopha (1), 3 species of Euceratia, and the introduced species Ochsenheimeria vacculella.
Adults - small with fairly broad forewings, hooked at the tip; at rest, the hooked tips project upward, giving a "duck-tailed" profile
Larvae - very active and react by rapid wiggling when disturbed (1)
much of North America and southern Canada
also represented throughout Eurasia
adults fly in summer
specialist feeders of new spring folliage on a variety of shrubs and trees (1)
Life Cycle
typically feed from a weak silken shelter and pupate in a dense, envelope-like cocoon (1)
Ypsolophidae was treated as a family by Dugdale et al (1999) in Kristensen N.P. (editor) Lepidoptera: Moths and butterflies. Volume 1: Evolution, systematics and biogeography. Handbook of Zoology. Walter de Gruyter. Berlin/New York.
