we found hundreds of dead moths that look like these, don't know if exact match, about five years ago all in the upstairs northern corner of our vacation home. My sister's home had same, only she was there as they were apparently emerging to fly. I thought that it was probably due to weather patterns, and perhaps cycles, like cicada's in the south. Anyone remember or had a similar experience of an explosive short term moth invasion? I don't know how they got into the house, but they all died in the upper north corner, so it was like they had a compass setting to go north.
