Caddisfly larva and emerging pupa are literally all the buzz on the trout stream throughout much of late spring, summer and fall. <\/p>\n\n\n\n

The adults typically live for about a month, just long enough to mate and lay eggs. Adults usually stay close to the water, and adult females lay eggs on or in the water (females of some species will dive underwater to lay eggs). Some females will lay up to 800 eggs .<\/p>\n\n\n\n

Here is an online video of the caddis fly life-cycle. (If you fast forward to the 5 mins 36 secs mark you will see great shots of a caddis pupa swimming on the water surface). The insect undergoes larval, pupal, emergent pupal, and adult stages. After taking flight, the adults mate and the females either deposit their eggs on the water surface or they swim down to the river bed to lay their eggs.<\/p>\n\n\n\n
