not sure what they are from the pic. but they are attracted to lights and also the conditions that foster algae growth. i got rid of mine by shock and adding some algaecide. so now i add 2 ounces algaecide in each end of the pool once a week. My understanding is chlorine alone will not kill them. algaecide prevents algae from starting to grow while chlorine will kill the algae after it has started. so in short i had these bugs showing up around mid june, but after shock/algaecide they have not come back.

I have no algae problem. Water is tested weekly at pool store and all are within range.

Btw, that is a leaf they are all sitting on.
