The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.
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,
