The Russian River is starting to pick up in terms of critters. First is Epeorus longimanus, followed by a Siphlonurus sp. Last are a couple of Ameletus sp.

Any ideas about the specific name of the Siphlonurus sp. would be greatly appreciated.

Who said we haven't been visited by aliens?! Those first two are for sure visitors from somewhere else...It's not "The truth is out there", it's "The truth is hiding in our rivers"...:)

Nice photos! Thanks!

It's a good deal more likely that they see us as aliens. They've been around a good deal longer and probably look on us as the bipedal pinkies who periodically bother them.:)

Nice photos! Thanks!


You're welcome.

Posts: 2Just bought house on Russian river. Love seeing mayflies hugging the doorframes in the early mornings. Reminds me of the east coast where I used to fly fish the Farmington and housatonic year-round.

When gardening I see insects in the dirt I've never seen before anywhere. They look like mayfly nymphs. They are anywhere from a millimeter to an inch long. They look like all-brown versions of Baetis nymphs, skinny, compact, perhaps 2 tails. They crawl over rocks, my planters, the dirt, anywhere.

Are there such things as terrestrial mayfly nymphs that live their entire lives close to rivers but on land?!?

If so, what variety are they? I want to create a ceramic address/nameplate at bottom of my driveway with a sketch of one of these things. Thanks.

Hansolo - my wife once said earwigs looked like mayfly nymphs.
