The main reason I prefer the scientific names (versus the common names) other than the point illustrated above, is that it narrows down the subtleties of the specific insect.
Case in point - Drunella
species; All Drunella's
(D. lata, D. cornuta, D. flavilinea, D. doddsi
, etc) change colors dramatically when they hatch. They tend to hatch in the surface film and then pop through the meniscus (like most Ephemerella
species). A freshly-hatched Drunella actually has a bright green (chartreuse) body, but within moments of riding on top of the water and being exposed to air their body dries to a medium/dull olive.
So depending on how much emphasis is placed on body color, an emerger pattern for Drunella
hatches (aka Western Green Drakes, Eastern Blue-winged Olives, Flav's in the west) should be dressed in bright green.
For example, when the D. cornuta's
were hatching on the Brodhead River back in PA, this was a killer flymph pattern. I tie them on yellow thread to bring out the green even more than shown here.
