Explanation of Names
Generic epithet Macaria is from Greek mythology, the daughter of Hercules. (3)
The genus Speranza is treated as a synonym of Macaria by MPG(4), Pohl et al. (2016)(5) and Pohl et al. (2018)(6) following Sihvonen & Skou (2015:142)(1), reversing Ferguson (2008)(2).
Numbers
More than 100 species in North America, listed under Itame and Semiothisa . 42 species in Canada (CBIF).
Size
Wingspan 18-35 mm (except in flightless females that have greatly reduced wings).
Identification
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.
Range
Represented throughout North America.
Habitat
Coniferous, mixed, or deciduous forests, plantations, parklands, and woodlots.
Season
Adults usually fly from May to September.
Food
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
Life Cycle
One generation per year, occasionally two.
See Also
Many common species are listed under Itame and Semiothisa in older publications.
