I saw this individual flying around as I was cleaning up the yard some. It seems he/she is a little out of range. According to butterfliesnadmoths.org their range is : "Boreal North America south of the taiga. Southern Alaska south to California, Nevada, and New Mexico; east to Newfoundland and West Virginia." I do not know where these wetlands are around here that they live by, since we have had a very dry and very warm winter. Also my lilac, which the adults like, the buds are only just turning green. It went to the crocus though.
