Western Ginger Quills



Like most common names, "Western Ginger Quill" can refer to more than one taxon. They're previewed below, along with 4 specimens. For more detail click through to the scientific names.

Mayfly Genus Ecdyonurus

These are often called Western Ginger Quills.
This fairly new genus holds some Western species that used to be in Nixe and were in Heptagenia before that. They are mentioned in books by those generic names. Ecdyonurus simpliciodes is especially important.

Mayfly Species Cinygmula reticulata

These are sometimes called Western Ginger Quills.
Cinygmula reticulata is probably the second most important species of Cinygmula behind Cinygmula ramaleyi, perhaps because the waters where it can be found in good numbers are often more remote. They have been reported as abundant in many high country streams of the Southern Rockies as well as the High Sierra's Eastern slope. An obvious difference in their coloration may be the easiest way to tell them apart. Cinygmula ramaleyi is more somber with a brownish body and dark gray wings and is often confused with the similar sized and colored Ephemerella tibialis, in spite of the difference in tail counts. Cinygmula reticulata on the other hand is a bright cinnamon dorsally with pale creamy legs and pale wings that are often a brilliant canary yellow. This is one of North America's most beautiful mayflies.

They were C. reticulata. The interesting thing is they were collected in May and were emerging along with Rhithrogena (March Brown). This seems to be an overlooked hatch since in some rivers it emerges very early, before runoff.

Keys in Needham's 1935 Biology of Mayflies point to either Cinygmula reticulata or Cinygmula gartrelli. IT seems to have “cross veins in costal half of fore wing only, slightly margined with brown” and “wings tinged withamber at base and along costal margin of both wings” (gartrelli) as opposed to “all cross veins of both wings faintly but broadly margined with pale smoky” and “wings entirely amber-tinged” (although there is a slight amber tinge throughout, just more pronounced in places) as in reticulata. However, wing length reported for reticulata (9 mm) is closer to this specimen than gartrelli (10 mm). Ventral (Ventral: Toward or on the bottom.) median marks are supposed to be “traces” for reticulata and “present” for gartrelli. Descriptions for both species involve semi-hyaline (Hyaline: Highly transparent, or glassy; usually refers to insect wings, especially those of mayfly spinners.) anterior (Anterior: Toward the front of an organism's body. The phrase "anterior to" means "in front of.") abdominal segments not present on my specimens. Distribution records suggest reticulate lives nearby, so I'm going with that, but I can't confidently rule out gartrelli.
