Insects of Cedar Creek
Order TRICHOPTERA
(Caddisflies)
Caddisflies (1262 NA spp) resemble small moths, but their wings are
hairy instead of scaly. Larvae are aquatic, most living in portable cases
constructed of vegetable or mineral material. They occur in both lotic
and lentic waters, but streams and well-aerated waters are generally more
diverse than stagnant water. 18 families are found in North America. Of
these, 15 families representing 270 species have been collected in Minnesota.
Only 25 species have been collected at Cedar Creek, but this number could
possibly treble with serious collecting. All families occuring in Minnesota
are underlined below and have an accompanying Narrative, whether or not
any representatives have been collected at Cedar Creek. Genera/species
collected at CCESR are in
boldtype in the Narratives.
The major Families collected at Cedar Creek are lentic (pond, lake,
marsh) representatives of the Hydropsychidae, Phyrganeidae,
Limnephilidae,
and Leptoceridae. Also collected: Polycentropodidae
and Molannidae. Hydroptilidae expected to occur here.
The other Families occur primarily in rapid flowing streams, small springs,
or large rivers; and these habitats are lacking at Cedar Creek.
