scientific name    Hemileuca eglanterina    

common name     Western Sheepmoth

Montane meadows and open woodlands. In AB, only found from Waterton N.P. north to the Crowsnest Pass

These moths are day-flying, and are found primarily between late June and mid July.

No other species in Alberta has the distinctive pink and yellow wings with black markings. The extent of the black markings is extremely variable, ranging from being almost absent to entirely black. The Sagebrush Sheepmoth has a similar pattern, but lacks the pink and yellow colour.

life history
This species is thought to have a two-year life cycle in Alberta, overwintering first as an egg and again the second year as a pupa. These moths have a very rapid flight and are usually difficult to observe.

The Western Sheepmoth has a very limited distribution in AB and may be sensitive to land use changes

diet info
McGugan (1958) states the main hosts are wild rose and ocean spray (Holodiscus discolor), which is not known to occur in Alberta. Other known hosts that do occur in AB include willow, Vine Maple, birch and aspen.

Southern B.C. and extreme southeastern Alberta southward throughout the western U.S.
