The moth numbers have continued to be low with 9 moths of 7 species on the 18th, 11 of 6 on the 19th and 9 of 6 last night. There were no new moths with one notable exception. Yesterday, there was a new Lymantriidae, Douglas Fir Tussock Moth (Orgyia pseudotsugata) on the wall behind the light trap. This appears to be the first record of a Douglas Fir Tussock Moth for Alberta. Apparently, this is not an entirely unexpected record as it was thought that it might occur in the western mountain region of Alberta in association with its host, Douglas-fir, especially during outbreak years. So far this is just a one off record but I will deploying my backyard light traps with interest over the next few weeks.
