Western Green Drake
During late June and early July rivers around Prince George, especially the nutrient rich rivers, have pretty good Western Green Drake (Drunella grandis) hatches. Some rivers also have Drunella dodsii. Although these mayflies are fairly large some anglers on occasion will confuse it with the Flav hatch (Drunella flavilinea)
that happens in late July/early August. Flavs look like Western Green Drakes but are quite a bit smaller.
To imitate Drunella grandis I developed the following pattern to imitate the newly hatched dun or sub-imago. The sub-imago stage is apparently unique to mayflies (Order: Ephemeroptera). The sub-imago will eventually go through another molt to become a spinner or imago that is sexually mature. The spinner that molts from the dun looks quite different. It has clear and transparent wings and a slimmer darker abdomen.
