}} Drepana arcuata, the arched hooktip or masked birch caterpillar, is a moth of the family Drepanidae. The species was first described by Francis Walker in 1855.[1] It is found from Newfoundland to Vancouver Island, south to at least North Carolina, South Carolina and California. The wingspan is {{convert|24|–|40|mm}}. Adults are on wing from mid-May through late-July. There is one generation per year in the north. The larvae feed on Betula papyrifera and Alnus species, which they may use as a medium to communicate. Sound is produced by shaking their bodies, drumming and scraping their mouthparts, or dragging specialised anal "oars" against the surface of a leaf. Larvae build communal silk shelters and the sounds may attract other larva to the shelter.[2] References1. ^{{cite web |url=http://www.entomology.ualberta.ca/searching_species_details.php?s=2774 |title=Species Page - Drepana arcuata |work=Entomology Collection |publisher=University of Alberta E.H.
