ANGLER’S CONCEITS, Part II
There are two species of Ephemerella mayflies in these parts, one of which is kind of a big deal on the lower Kinni. Or at least it was until the City released all that sand into the river. Anyway, because of its rather light color, people got into the habit of referring to it as the Light Hendrickson. Traditionally the Light Hendrickson was an angler’s term for E. Invaria but there were at least two other species that were lumped together under that angler’s term. It wasn’t until about 2005 when Clarke Garry, Ph.D, correctly identified it as E. Excrucians that we knew what it was. Now you’d think that anglers would welcome that news, but you’d be wrong. At least one of my customers was visibly upset by the news and shouted, “No! It’s the Light Hendrickson!” He got over it but it’s a clear illustration of another angler’s conceit. Is hanging on to an inaccurate term really more important than a positive ID from a scientist?
I used to go to the Fly Shop when Bob and Jean owned it to find out what was hatching on the Kinni. Bob always said the same thing, “Blue Wing Olives.” I was always kind of disappointed by that because I kept expecting to find something else to fish over. However, Bob was right because so many Baetis species are bivoltine means that they’re almost always available to the trout. But they are not all olive. The vast majority of the samples I’ve collected have been tan. Don’t believe it? Get yourself a little insect net and try it yourself. Baetis could be olive, but they’re more likely to be tan, brown or even grey. It’s hard to break a habit. And the one I hear most often is, “Are the Olives hatching?”
OK, one more and then I’ll stop. For decades people who tie imitations of the Trico spinner have tied them with three, widely separated tails. Back in the ‘70’s I watched Tom Andersen tie some of these flies for Bob and he artfully positioned his dubbing needle underneath the tail filaments, spread them apart and held them for a second or two until they stayed in that position. Look at the selection in any fly shop and you’ll see many examples of this style. Gary Borger once opined that a trout’s IQ was 6. Six. Do you really believe a trout would reject your Trico imitation if it only had two tails? With that robust thorax and spent wings why would the fish focus on the tails? They probably don’t, and to bolster my opinion there’s this; Perry Palin is one of the better tiers around here and he’s been tying a very effective Trico pattern for years using a few grizzly barbs for the tail. They’re not long, they’re not spread and they’re definitely more than three. And it works fine.
