Hi, I have been finding these little almost moth-like insects in my basement this winter. They are a little smaller than a housefly, and seem to come in waves. What are they? And are they a pest? Any thoughts are most appreciated. Thank you! Sophie Bréchu-West
This looks like it could be a drain fly. They are fuzzy, slow and hold their wings out like that.
Please take a look at this page on them and see if it fits:
