Habitat Found on aquatic vegetation, rocks, logs, coarse detritus and fine sediment. Different species may inhabit flowing and standing, permanent and temporary, fresh and saline, pristine and degraded habitats.
Feeding Information Most species consume organic particles found on substrate that they live on. Some build vertical tubes to extend their body and gather particles in a circle around the tube.
Water Quality Tolerance Wide range of tolerance levels, but a relatively large proportion of Chironomidae larvae usually indicates poor environmental health and pollution. Some species are very tolerant of toxic substances and develop deformities on their mouths.
