|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.
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
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.
