A Message from the Director

April 24, 2019

Residents may be seeing what appear to be large dark mosquitoes, sometimes in swarms, however these are Chironomid Midges. It is a bit early in the year to be seeing them, but they emerge each year just ahead of the first mosquitoes and do not bite. Not being a vector of any diseases, we do not treat them, although the swarms can be a bit unnerving or irritating. They do not last long after mating and deposit their eggs in large permanent bodies of calm water such as the Corps ponds and Ecology Park pond.
