Synonyms and other taxonomic changes
Cricotopus van der Wulp 1874
Nearctica lists 63 species.
Within Orthocladiinae light bands on the first front tarsal segment and the abdomen point to Cricotopus. The reverse is not true -- some species of Cricotopus are not banded and need to be identified by less obvious characters.

Larvae are nearly indistinguishable from Orthocladius (Orthocladius); despite the differences in adult color the genera are closely related.
"Larvae are found in a variety of aquatic habitats, where they are often associated with plants. C. (Isocladius) species tend to be more common in lentic conditions; C. (Cricotopus) species are more common in lotic situations; C. (Nostococladius) is associated with the blue-green alga Nostoc. Some Cricotopus larvae may be economically important as pests in rice fields (members of the C. (I.) sylvestris group) and as biocontrol agents for nuisance aquatic plants (C. (I.) lebetis for hydrilla). Cricotopus bicinctus and C. infuscatus are tolerant of many types of water pollution."(1)
