Non-biting Midges (Chironomidae)
This family of midges also proved to be dominant in the School Malaise Trap Program as they were the most abundant and most diverse family of insects in the collections. Some 7000 sequences representing likely 250 species. Only about 1/5 matched records on BOLD that had a species name. The rest has not been identified so far or represents a new addition to the DNA Barcode library.
Waltzing Fly (Prochyliza xanthostoma)

The Waltzing Fly is a carrion fly commonly found in North America. The larvae of this fly species often develop inside the bones of freshly killed animals (e.g. deer, moose) and in their final stages, they fall into the surrounding soil to pupate and soon after, emerge as adult flies. In Ontario's Algonquin Park, waltzing flies typically breed in early spring on the carcasses of moose that did not survive the Winter. In March and early April, they are one of the most plentiful insect species in the Algonquin forest. Males and females look quite different, with the male having larger antennae, head and forelegs compared to the female. These differences are due to the male’s unique courtship and combat behaviours. Males battle to defend their territory (see video) and dance to attract mates hence the name Waltzing Fly.
