gnats, midges??? Or ??

Asked April 21, 2016, 9:30 PM EDT

Within the last couple of days we've had a major hatch of some sort of small flying insect in front of our house in a fairly dense subdivision on the west side of Loveland,

These creatures are very small, greenish in color, are winged and have appeared in flying swarms on the warmer side of our house.

Any idea what they are ?? Their life cycle? Will they go away soon? Or?

Probably one of the non-biting midges of the family Chironomidae. These are often the most common insects associated with ponds and lakes, the larvae feeding as scavengers on bottom sediments.

Adults emerge from the water to mate and lay eggs; they sort of look mosquito-like but are harmless. Adult emergence can occur throughout the year but the major first emergence follows the period when the water in lakes/ponds "turns-over" when it reaches 38F - the temperature when water is heaviest. Which should be about now.
