Lype diversa
net tube caddisfly
Lype diversa is a species of net tube caddisfly in the family Psychomyiidae, first described by Nathan Banks in 1914. It is a small, inconspicuous caddisfly found in freshwater habitats across North America. Like other members of its family, larvae construct silken capture nets to filter food particles from flowing water. The species is among the least documented in its genus, with sparse occurrence records and limited ecological study.
Orthocladius
Orthocladius is a genus of non-biting midges in the family Chironomidae. Larvae are aquatic and construct silk tubes that serve as microhabitats for associated microbial communities. The genus includes species adapted to diverse freshwater environments, including streams and hygropetric habitats.
Protoplasa fitchii
Protoplasa fitchii is a species of primitive crane fly in the family Tanyderidae. It is one of the few North American representatives of this relict family, which retains many ancestral dipteran characteristics. The species is primarily known from eastern North America, where larvae develop in aquatic or semi-aquatic habitats. Adults are rarely encountered and poorly studied.
