Common Forestfly - Zapada cinctipes
General Description
This is the most common genus of the family Nemouridae in the Rocky Mountains. Zapada species are found in almost every flowing water habitat in the northern Rocky Mountains and Z. cinctipes is the most vagile species in the whole group
The genus is distinguished by the presence of two pairs of cervical gills, one on the inside and one on the outside of the lateral cervical sclerites
Zapada species are abundant in accumulations of leaf material and probably act as shredders of allochthonous material in heterotrophic lotic ecosystems.
