I collected this mayfly after user Al514 tipped me off to the presence of some Leptophlebia
mayflies I didn't seem to have yet with his ID request
of a male dun. This seems to be of the same species. I also collected a female spinner
. Based on that spinner, I can tell that this is either Leptophlebia cupida
or Leptophlebia nebulosa
, but I can't tell which.
Unfortunately none of the specimens I collected made it through the hot, sunny day very well. So the pictures aren't great, but they're better than nothing.
