I still can't figure out what they took the Adams for. The only
bugs in the air were some dragon and damselflies, but they were off in
color and size, and the fish weren't rising to them that I could see. I
don't know if the Adams might resemble an emerger or if it just looked
like some sort of generic food to them. Whatever it was, it saved me
from a fishless day on the water.

So has anyone else had luck with the Adams on both warm and
coldwater species?

well, this is not a precise response to your query, but it evidences a
similar phenomenon. i went up to brevard, nc, in the blue ridge, to pick up
my son a couple years ago, where he was visiting a family friend. he had
found a little pond, and had been spin fishing it for bass. he had caught a
few 10-14 inchers during his stay. it was like mid-august, and hot. he
wanted to go fishing one more time before we returned home, so i grabbed the
only gear i had in the jeep--a 4wt with a 16 light cahill on a 5x
tippet--figuring to just keep him company, or maybe grab a bream or two.
so i'm standing on a dock, tossing a few perfunctory casts in a half
circle, and the damn cahill disappears in what appeared to be the surface
disturbance one might expect from the entry of a five pound piece of granite
into the pond. about a three pound largemouth. fooled around with him for
about ten minutes. the cahill looked ludicrous in his lips.
no bugs of any sort in the air. no possible way there had ever been a
mayfly hatch in that water.
anthony, my boy, wandered up as i released the bass; he just shook his
head and said, with an air of resignation, "random, dad".
