Bug question

[sgrim]

I'm not good with insect identification. I went up to the Tully this weekend and in addition to a ton of caddis, which I can recognize, I saw sporadic flights of a large(r) cream mayfly. Maybe size 16 or larger. Was I seeing sulphers?

Sulphers would be my guess.

Or Cahill’s. They are large, at least the ones I have seen.

For a few years I thought they were sulphers.

Cahills are large (about size 12) and have two tails; sulfurs are smaller (14-18) and have three tails. Easy to distinguish.

It's the right time of year for sulfurs, and the Tully usually has a good hatch of the,.
