Caddisfly Larva - Family Phryganeidae

I was trying to get a shot of the caddisfly's case, but this whirligig beetle kept trying to eat the caddisfly. I eventually had to remove the beetle before it killed the caddisfly.

This larva was quite large. I didn't remove it from the case, but would guess it to be around 40 mm long. It had an orange head with dark brown stripes. Its case was made of leaf fragments that had been cut and stacked like rings.

Habitat: Collected from a small, woodland pond
