Cinygma, maybe dimicki? - Cinygma - Female
Cedar Creek, Clark County, Washington, USA
June 3, 2022
Size: 11mm
Does this look like Cinygma dimicki to you folks? Not big numbers but I’ve seen a few of these medium sized (body and head length, not counting tails, 11mm; forewing length 13mm) chartreuse mayflies the last two times I fished around the mouth of Cedar Creek (elevation around 300’), a tributary of the North Fork Lewis River in Clark County, western Washington, USA. Found this one June 3, 2022.
