Invertebrate Photographs - Trichoptera (caddisflies)
The Trichoptera are one of the largest groups of aquatic insects and closely related to the Lepidoptera (moths and butterflies). All of the families are found in cool, running waters and some have adapted to slower and warmer waters. They are known for their portable cases, nets or retreats, and caddisfly families can be classified into the following groups: Free living (Rhyacophilidae), Saddle-case makers (Glossosomatidae), 3) Purse-case makers (Hydroptilidae), 4) Net-Spinners (Philopotamidae, Psychomyiidae, Polycentropodidae, and Hydropsychidae), and 5) Tube-case makers (Phryganeidae, Brachycentridae, Limnephilidae, Uenoidae, Leptoceridae, Helicopsychidae, Odontoceridae).
We have photos of the following families below: Glossosomatidae, Hydropsychidae, Limnephilidae, Lepidostomatidae, Leptoceridae, Philopotamidae, Phyrganeidae, Polycentropodidae, Rhyacophilidae, and Uenoidae. For a more extensive look, visit our Web page on caddisfly families.

All photographs marked with ESC were taken at USEPA's Region 3 Environmental Science Center at Fort Meade, Maryland. Many thanks to Dr. Dave Russell, invertebrate biologist, for arranging the instruction and assistance with the use of the Olympus SZX12 miscroscope with an Olympus model DC330 optical mount. Other photos were taken under contract to EPA by EcoAnalysts, Inc. Also see our pages on caddisflies and caddisfly families for more information.
