Caddisfly Identification
Searching for and identifying caddisflies can be challenging, particularly if they dwell near moths. However, caddisflies can be distinguished from moths and butterflies by their underdeveloped mouthparts: caddisflies do not have mandibles.
Searching for and identifying caddisfly eggs is relatively easier than identifying them at other stages of their life. Eggs are most commonly found at the bottom of streams or rivers. They are tinted green and are covered by a thin layer of what resembles cement.
It can be challenging to identifying caddisfly larvae because they are similar in appearance to caterpillars, as well as to other species of the Order Trichoptera. However, caddisfly larvae are aquatic and spend most of their time underwater. Some species are also easily identifiable by their larval casings, which are formed from twigs, leaves, sand and other scavenged materials.
