The largest and most well-known hellgrammites belong to this genus, although in my collecting experiences the fishflies of Nigronia seem to be more common in trout streams.

The First time I saw one of these things was as a kid. We were playing around a woolen mill in old Kezar Falls Maine.
Turning over a damp old pile of wool revealed a number of adult Hellgrammites. At the age of 12 or 13 these were the scariest things I had ever seen.... still very intimidating. I remember trying to get them to bite sticks and my shoe... which they happily did once I started poking them.

Now at the age of thirty *mumble mumble* This insect has come into my life again.
After opening my little tackleshop and selling flies and gear for about a year, it was an embarrassment that I couldn't catch the Browns surfacing all over the place down on the river.
I finally got one by accident, cut open its belly and found... thats right... A dobsonfly nymph.
Although I believe they were really feeding on dragonfly or damselfly nymphs (as they were chasing and feeding near the top)
The story of my trouts belly told a different tale.

Some time at the tying bench, with a few pieces of yarn and marabou and now those old browns are no problem at all!
