I found a bunch of baby bugs with wings, all dead, stuck to the front of my light fixture outside today. What

kind of bug is this? I had the house sprayed last year for termites because a mound was spotted...I never did see any termites. We had a huge tree fall in our front yard about 3 weeks ago, which we had cleared out the following day. Were the bugs possibly eggs in that tree?? Why are they all dead and stuck to the light like that?? I have never seen anything like this before.
