Midges

With all the rain we have been having, water has been collecting in a huge white plastic drum in the yard and needless to say, insects find their way to it to breed.
These Midges (Family Chironomidae) are very small, about 3mm or he size of a pencil point, in length. The Larvae which you can see in the top photograph are maybe half an inch in length. In the one below, it shows some of their development stages they go through.
Larvae feed on decaying organic matter and they occur in almost any pool of water.
The males have very long, fan-like antennae and have blue-ish wings. They have poorly developed mouthparts and the adults of some of the species do not feed at all.
They are sometimes easily confused with mosquitoes and may form huge swarms when mating.
