Description
Habitat More species are found in different sizes of still water than in flowing water, ideally among plants in shallow habitats. Also found on muddy bottoms, accumulated plant debris or temporary habitats.
Feeding Information Both larvae and adults have strong mandibulate mouthparts which help various species to feed on a variety of diets.
Water Quality Tolerance Species range from facultative to sensitive when introduced to a substance, or other types of environmental stress from human activity. Useful for biomonitoring pollution.
