Diptera larvae can be found in a vast array of habitats: seeps, creeks, rivers, waterfalls, bogs, ponds, lakes, hot springs, tree holes, epiphyte reservoirs, pitcher plant’s liquid, soil, mud, sand, sap, decaying vegetation, dung, putrefying animal matter, wounds of plants and animals, bird and mammal nests. These larvae can be found feeding in all these environments, and in forest and meadow eating leaves and buds and plant roots. They can also be parasites of mammals, birds, reptiles, amphibians, insects, and other creatures.
The larvae shown on this page were found in damp under-bark habitats in Upshur County forests. The larva in the upper picture—with its web and slime environment—Paul Beuk comments may be family Keroplatidae.
