scientific name    Eupithecia lachrymosa    

habitat
Woodland and shrub.

seasonality
Adults are on the wing in Alberta from mid May through early July.

identification
A small dark grey-brown geometrid, slightly above average in size for the genus Eupithecia (1.9-2.4 cm wingspan). Markings obscure except for a fairly prominent dark forewing discal dot. The presence of dark brownish shading along the cubital vein at the bases of veins 3 and 4 and short dark transverse dashes on the postmedian line can be used to identify some specimens. However, the genitalia should be examined for positive identification. The square shape of the valves with a prominent median costal process and the narrow lyre-shaped 8th sternite in the male, and the very long appendix bursa and an almost completely sclerotized ductus in females will identify lachrymosa (Bolte, 1990).

life history
Poorly known. Adults are nocturnal and come to light.

conservation
A fairly widespread western species; no reasons for concern.

diet info
Reported hosts include willow (Salix), Paper Birch (Betula papyrifera), Ceanothus, and Alder (Alnus) (Prentice, 1963; McKay, 1951; McGuffin, 1958).

range
A western species, occurring from central Saskatchewan west to southern Vancouver Island, north to Tweedsmuir Park, BC and Tolman Bridge in Alberta, south to California. In Alberta found in wooded areas in the grasslands region, north to Tolman Bridge Recreation Area.
