It was another good night and I have now exceeded last year's number of backyard macro species at 150!  The bait trap continues to pay dividends with a new Underwing, Semirelict Underwing Moth (Catocala semirelicta).  Thanks to Gary Anweiler for identifying this species.  I initially thought it was Catocala meskei but the habitat is wrong and after closer inspection the wing pattern is more like semirelicta.  It seems that Underwings have been appearing somewhat earlier this year continuing the unusual nature of some Lepidoptera sightings in Alberta.  There were 81 moths of 25 species in the traps plus 2 noctuids that I haven't confidently id'd yet.  Including the Semirelict Underwing, there were 2 new backyard species last night, the other new moth being a nice Geometrid, Zenophleps alpinata. There was also one new backyard species for the year, Euxoa ochrogaster.  I'm including photographs of a Great Gray Dart (Eurois occulta), as this was the first one I've had this year that was undamaged and another Olive Arches (Lacinipolia olivacea) that shows some interesting rosy hues  The normal form of Olive Arches I see in my backyard has green hues.
