These are Ecdyonurus nymphs with Symbiocladius parasitizing them. They were collected from Mill Creek, a tributary of the Russian River. Symbiocladius are a member of Diptera, the true flies. They attach themselves behind the wingpads and grow to maturity there without harming the Ecdyonurus nymph. They parasitize Paraleptophebia and Rhithrogena as well though not in this area.

Fascinating, Mark. Are they just attaching themselves for pupation or are they feeding off them?

Kurt-

They feed off them. They attach themselves and feed off haemolymph (bug blood) and associated tissues.


Eric-

You're welcome.
