Today we will explore the group of mayflies whose nymphs burrow - at least most of them do.  This includes some of the largest most showy (and exciting from a fly fishing perspective) mayflies - such as Hex's and the Green Drake.   As promised in the episode, here is a link to my wife's pattern, the Hexamongous - http://www.flyfishinginnh.com/forum/showthread.php?t=4222

Here is the pattern too, in case the link gets broken:

Hook: Daiichi 1270 Size#8 Thread: Brown Tail: Wood Duck Flank Body: Cream Rabbit Dubbing Rib: Light Cream Floss Back: Turkey Tail Fibers Wing: Wood Duck (Tied in as a loop wing) Legs/Throat: small dark under feather from wood duck - often attached to base of wood duck flank feathers (or mottled brown hen as modified in the post).
