Characteristics Caddisflies are related to Lepidoptera and resemble small hairy moths but their wings are covered in dense hairs rather than scales and they lack the typical curled proboscis of most moths and butterflies. There are approximately 14500 described species most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts.

The Characteristics of the Insect Order Trichoptera Biology The trichoptera insect order consists of numerous species of moth-like insects called caddisflies that grow to be less than one inch long. The head and thorax are also usually hairy. Trichoptera characteristics

Only aquatic Diptera outnumber them in species and ecological diversity. 02-05 inch 6-12 mm. Feeding mainly on aquatic invertebrates Hydropsychidae use silk nets to catch their prey. Trichoptera characteristics

The larvae of this species measure 034 to 052 inches 85 to 130 millimeters in length. Trichoptera larvae are aquatic and display a pair of hooklike appendages at the apex of the abdomen.

The insect order Trichoptera Kirby or caddisflies contains approximately 15000 described species found on all continents except Antarctica Holzenthal et al 2011The order is exclusively aquatic in the larval and pupal stages except for a very few terrestrial or semi-terrestrial and brackish-water species and one family whose members are exclusively marine. During the day they hide in cool moist environments such as the vegetation along river banks. The antennae are very long. Trichoptera characteristics
