General Description
Within this mayfly genus are several species known to fly-fisherman as "Green Drakes". The more abundant one is D. grandis, but D. doddsi is shorter and burlier looking. This species has a streamlined, flattened body style and has evolved a suction cup of hairs on the underside of the abdomen to allow it cling to rocks and cobbles in very fast sections of rivers. The adult duns look much like beefy blue-winged olives, with green to olive abdomens and 3 tails, however the body ratio is much shorter. These are fairly common in the fast flowing riffle areas of small, cobble streams to larger trout rivers throughout Montana including the upper Yellowstone and tributaries such as the Boulder River and Smith Creek to upper Missouri River streams such as the Gallatin and Big Hole and throughout west of the divide streams. Adults hatch in late spring/early summer.
Phenology
Larvae take 1 to 2 years to develop depending on watewr temperatures and adults hatch in late spring to early summer (the Green Drake Hatch).
