Tortricidia testacea

University of Alberta E.H. Strickland Entomological Museum Read more about this collection »

SeasonalityAdults have been collected in Alberta in June. IdentificationA small (1.5-2.5 cm wingspan) broad-winged moth with rust or yellow-brown forewings and tan-tinted white hindwings. The forewings are essentially unmarked, with a diffuse slightly darker median band reaching the apex. The veins are all slightly darker and are visible against the ground. The hindwings are white with a very light tan tint, and with the brown fringe forming a narrow terminal band. In shape and size testacea resembles a small gemetrid moth, but the color and pattern will separate it, as will the different wing venation. Tortricidia testacea is the only member of the family Limacodidae (Slug-catterpillar Moths) found in Alberta.

Life History
The caterpillars are short-legged and slug-like, and give the family their name, the slug-caterpillar moths. They are solitary defoliators of deciduous trees. In Alberta there is apparently a single brood each year,…
The caterpillars are short-legged and slug-like, and give the family their name, the slug-caterpillar moths. They are solitary defoliators of deciduous trees. In Alberta there is apparently a single brood each year, with the adults emerging in June. The adults are attracted to light.
Conservation Rarely collected in Alberta where they are at the northern edge of their range. Diet Info
No Alberta data; elsewhere a variety of hardwoods have been reported as hosts, including oak (Quercus), beech (Fagus), birch (Betula), chestnut (Castanea), wild cherry (Prunus), hickory (Carya) and Mountain alder…
