Drepana arcuata, the arched hooktip or masked birch caterpillar, is a moth of the family Drepanidae.

[1] It is found from Newfoundland to Vancouver Island, south to at least North Carolina, South Carolina and California.

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.
