Itame (in part)

Semiothisa (in part)

(Macaria includes almost all species formerly placed in these two genera, according to Scoble et al)

In 2008, various species were transferred into Speranza, Letispe, Epelis, and Psamatodes.

more than 100 species in North America, listed under Itame and Semiothisa at (nearctica.com)

42 species in Canada (CBIF)

wingspan 18-35 mm (except in flightless females that have greatly reduced wings)

adults of most species have light gray or brown wings (a few are yellow or white) usually with dark markings along the costa, and a dark discal spot in a number of species; some species are unmarked, but many have lines and speckling that ranges from dark and heavy to pale and indistinct - the range of variation in pattern and color makes the genus difficult to describe in general terms

adults usually fly from May to September

larvae of many species feed on leaves of coniferous trees; some species feed on broad-leaved trees or shrubs, and a few on herbaceous plants
