Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Hello everybody!

My name is Leonardo I´m master in ocean sciences and limnology and I work with freshwater isopods of the genus Caecidotea.

Maybe someone already knows me, but my problem is this ...

I'm going to start a new research work about this genus and I need some specimens from the type locality of Forge Creek Valley, Philadelphia.

I sent mails to many collections of crustaceans but they can't help me.

I hope someone on the forum can give me a little help, would be great.
Thanks
Greetings from Mexico City!
