Assorted Limnephilidae

(case length approx. 0.8 cm)

There are many varieties of Limnephilidae in the McKenzie, using all sorts of materials for their cases. This one seems to have a thing for using fir needles along with its gravel. The thing to the left is another Limnephilidae that lost its case -- it spent most of its time undulating its body to get oxygen.

(case length approx. 1.0 cm)

This is another one... The case is gravel, with fir needles

(case length approx. 1.8 cm)

And this is another one, though probably its a young October caddis. The case is made up almost entirely of small pieces of bark and wood.
