The row of dark black spots on the underside of the forewing makes it easily recognized. They frequent flowers and when perched often hold the wings folded over the dorsum, thus showing the distinctive spots. Wing span is about 12 mm. The caterpillars are small, slug-like and well camouflaged on foliage of mesquites.
