Although the total number of moths was fairly low, only 34 of 16 species, there were a few very nice moths in the traps last night. Two were new for the year and one appears to be a new species that I haven't identified yet. The two new, eagerly awaited, species were White Underwing (Catocala relicta) and a White-lined Sphinx (Hyles lineata). This is the first year that I have had two species of Sphinx moth in my backyard, the other being Sphinx Gallium.  Another moth of interest was the Eastern form of the Semirelict Underwing (Catocala semirelicta).  The eastern form is the less common form in Alberta and has a black streak running along the inner edge of the forewing making it easy to identify.  For me this was a good night!
