Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

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.
Best regards,
