Yes, this was attracted to my porch light. It is the only one I have ever seen though. I was just reading that they are parasitoids of spiders well that makes sense as my porch is "infested" with orb weaving spiders-most of which come out only at night!

Exciting!

This is a small-headed fly, family Acroceridae. Not commonly seen, so great find! It will also be a new species (and likely new genus) for the guide. Hope one of our dipterists can give that to you.

While I'm not familiar with the species, the genus is Ogcodes. These are day fliers and probably had been a parasitoid on one of the spider species on your porch. A very nice picture! I'm envious.

No, sorry about that. This is Ogcodes dispar and probably female. Both sexes of rufoabdominalis should have a black thorax making them obviously bicolored (but the reverse of this one). Males of O. dispar are typically yellow-orange all over, while the female is darker (especially the abdomen).
