Entomology (Study of Bugs)/insect


I am a custodian at a school that has a septic system of its own. In this building (20'x20') there is moving and standing water. there are MANY flying bugs that resemble mosquitoes but are NOT.they lay their eggs in the still water. they love to cling to the cement block walls.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
