Commonly known as the "net-spinning caddisflies," larvae of this family create silk webs to catch floating debris and small aquatic organisms for food. Species like Hydropsyche are frequently found in this family.
Referred to as the "free-living caddisflies," these larvae do not construct protective cases. Instead, they roam freely, preying on other small aquatic organisms. Rhyacophila is a commonly known genus in this family.
This is one of the largest families of caddisflies. Often called the "northern caddisflies" or "case-making caddisflies," many of the species in this family create cases out of plant material. A notable genus in this family is Limnephilus.
Known as the "long-horned caddisflies" because of their long antennae. Triaenodes and Oecetis are two well-known genera in this family.
The larvae of this family build square, log-cabin-like cases out of small sticks. Brachycentrus species are commonly encountered in cold, fast-flowing streams.
Often called the "giant casemakers," these are some of the largest caddisflies. Larvae typically build cases from plant material. The genus Phryganea is well-known in this family.
