In the family Chironomidae the eyes are large but not contiguous, and the ocelli are lacking. In most Chironomid groups the males have strikingly plumose antennae of 6-15 flagellomeres; females' antennae are not plumose and have 4-7 or 10-14 flagellomeres (Brown, 2009).
Of the legs, the forelegs are the longest and males often extend them to the front as if they were antennae.
Some larvae are predators, others parasites, while others feed on plant material (mining in leaves, for example). Adults live only for a matter of hours to several weeks, and either do not feed or else feed at flowers or on honeydew (Brown et al, 2009).
