Ennomos subsignaria

Ennomos subsignaria, the elm spanworm moth, is a moth of the family Geometridae.

The species was first described by Jacob Hübner in 1823.

It is found in North America from Texas (south) to Alberta (northwest) and east to the Atlantic coast.

[1][2] It is recorded infrequently in Great Britain through accidental importation in asparagus.

The larvae feed on elm, apple, birch, maple, and oak.
