Took me a while to work out what these really tiny things were attracted to the lights of the house. No more than 2-3mm but with distinctive wing shape.
No interactions present.
The very sharply-pointed wings and few scales are at least typical of this genus.
Please feel free to join in discussions of these things on the forum, where we're trying to get our heads around them...
