This morning I had some really small bugs coming off. I was able to grab some off of a spider's web. I know the small blackish guys are Tricos but I am not sure what the little bigger guys are, which was more abundant. Any thoughts?

A #20 pheasant tail dropper with a #20 comparadun did catch several trout. I didn't see enough Tricos to go down to #24's.

Hard to say. Could be Acentrella.

Konchu, thanks. I was thinking "Pseudocloeon". Of course, you probably changed that on me too. :-)

They also could be Plauditus. Most of the Plauditus and Acentrella species were known as Pseudocloeon at one time. I'll bet Taxon has some ideas, too.

And just to be clear, I had NOTHING to do with the Pseudocloeon thing.

As Konchu suggested, I have some ideas, but would prefer to get some additional information from you before sharing them. I have annotated your photo with two comparable linear dimensions. Please ignore the 1.40", as it was based on photo enlargement.

Anyway, the first dimension is the length of one of the mayfly bodies. The second is the length between two lines on the palm of the hand of the person holding the mayflies. Your assignment, should you choose to accept it, is to measure the "actual" length in mm between the two lines in the palm.

Also, it appears to me that the mayfly I dimensioned has two tails and no hind wings. Can you confirm either of my beliefs from your observation of the actual specimen?

Twice as long as the Tricos. :-)

I kept them in a flybox but they are all dried up so they are just a mush ball of dead bugs. Besides, I can't see those lines in my hand like that anymore. You should see me trying to thread my 7x tippet through the eyes of those little hooks! Thank goodness for Walmart 2X reading glasses. :)

John, Taxon has used dotted lines, next to the left hand 1.40 to designate the lines he's asking about. They came out faint, but visible when he reposted the photo. If he doesn't darken or enhance them a bit, reading glasses (which I too must use) will make them clearer.
