Yes....but I suspect there are stretches of the Delaware/Susquehanna that have mud bottoms with a little slower current flow than say the Beaverkill = often producing heavier hatches of that specific mayfly... Beats me why...they just seem to thrive, in greater numbers, on the slightly slower current...even in still waters(bogs/ponds/lakes) up here. Have a pic of them covering a parked car's windshield & hood in a lot in Greenville, just off the water(Moosehead Lake's southern end)...have to find it on a CD(will update when found).. Surprised, with the size of that hatch down there, that someone hasn't produced a B-SciFy/Horror flick from it yet...
