General Description

A bright yellow geometrid, with the PM band of reduced to a few maroon-brown spots. The AM band is usually only present as a brown spot at the forewing costa; variable maroon speckling overall. Difficult to separate reliably from X. sospeta without genitalic dissection, see McGuffin (1981). Sospeta is slightly larger and paler yellow than urticaria, with narrower and relatively smaller maroon markings.
