Reproduction/Life Cycle

     Insects that are members of the order Trichoptera are considered to be homometabolous, meaning H. betteni go through a total of four stages of development in a period of around one year. During the summer months, the adults appear in the largest numbers. After mating occurs between a male and female, the female deposits its eggs on rocks located under the surface of a river/stream or along the shore of the river/stream. On average, adult H. betteni live three to five weeks
    About one month after the eggs are deposited, the larvae hatch. The larvae then travel out on their own, later constructing silk nets (as previously mentioned in Nutrition). After achieving full growth, the larvae build a structure around themselves similar to a cocoon made of silk and small pepples/sand particles (Fowler). This stage, called the pupal stage, lasts from around two to three weeks. After this time period, the adult H. betteni emerges from the "cocoon." The life cycle is then repeated (Net-spinning caddisfly larvae).
