I do know these nymphs are biggies alright, but just what is the average size of them, like their length in "mm"?
What is this supposed to look like, example please.

According to McCafferty, Gomphid (Clubtail) nymphs generally measure from 23-40 mm. (and rarely as long as 65 mm.) at maturity.

Posts: 1Not sure what size they grow to before ecdysis where you are, but in Africa they grow to 3 inches long - I watched one hatch and fly off then measured the empty shuck. Trout go ballistic for them!
