A freshly emerged female Drunella lata dun.

I saw something strange flying around near the streambank, fluttering on and off the water's surface, so I went to check it out. I didn't recognize the wing profile in flight, and it's no surprise! These two caddisflies were joined mating, and they were very reluctant to let go.

Here's the bottom of a freshly emerged male Drunella lata dun, showing a lighter shade of olive than the specimens I photographed with my better camera in the evening.

I photographed the underside of this March Brown dun right after it emerged so that I would have the exact color for an imitation.

I didn't manage to collect a nymph, but here's the hollow shuck (
Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.) left over from an emerged dun, showing the basic pattern of the nymph.

This dragonfly got stuck in its shuck (Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.) trying to emerge, so it was just crawling around on this rock.

I'm not sure what the caddisflies in this tight cluster are doing, but I'd guess it has something to do with mating. They scooted all around the rock, with some flies leaving the cluster and new ones coming all the time.

After I took this photo, this specimen was swept out of this tiny pool into a riffle downstream, where I swooped it up with my aquarium net and brought it home to photograph. See it up close here.
