Chironomids as a group are very diverse in their life histories and exhibit a variety of behaviours during their development. Due to their species ambiguity and this diversity of behaviours, there is much controversy in research on their feeding habits, particularly as adults.
Many reference sources in the past century or so have
repeated the assertion that the Chironomidae do not feed as adults, but an
increasing body of evidence contradicts this view. Adults of many species do,
in fact, feed. The natural foods reported include fresh fly droppings, nectar,
pollen, honeydew, and various sugar-rich materials.
