Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.

I have always wondered if there is a list of the colors of insect eggs or insect egg sacks by order?
As tiers, we often try to imitate the female egg layer in our flies. However, I have seen different colors used. For example, I have seen both yellow and green used for egg sacks on caddis patterns.
This summer, during a Salmonfly "storm", I found orange eggs on the females. Although, most others say such eggs (or egg sacks) on Salmonflies are black?
Good, scientific info would be welcomed!
Thanks, in advance.

Hi Byron-
Don't recall ever having encountered a list of ova color by insect order, or by anything else for that matter. However, it would seem to be useful information to have.
