Dr. Charles David of the Guernsey Biological Records Centre identified these two mating insects as belonging to the family psychodidae. They are known as drain or moth flies. These insects were mating under a fern leaf a few feet away from a composter set in a sunny location in my garden in St. Peter Port, Guernsey. They were photographed on the afternoon of 28 February 2009. File No. 280209 2113 ©RLLord fishinfo@guernsey.net - sealord
