SilverCreek 0 Report post Posted April 23, 2020 Thank you. That makes sense since the naturals vary in coloration and even if they didn't, the colors do not have to be spot on. Gary Borger discovered that over 20 years ago and published the BCS (Borger Color System), a chart of "close enough" color chips to match the hatch. There is also evidence that the female adult of insects tend to be larger than the males. So size varies also. See: http://www.troutnut.com/topic/1846/Male-or-female "The females of most mayflies, caddisflies, and stoneflies are larger (on average) than the males. Most (but not all) male mayflies have larger eyes than females. Quote Share this post Link to post Share on other sites
WJG 0 Report post Posted April 24, 2020 SilverCreek, I make my life more complicated by comparing the material's colour on the hook when wet to the bug being imitated. Some dubbings change colour drastically when dunked. Quote Share this post Link to post Share on other sites
SilverCreek 0 Report post Posted April 24, 2020 Colors generally darken when wet. That is why you compare nymph dubbing when wet. See the series of posts on this thread Quote Share this post Link to post Share on other sites
