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.

Ephemerella mucronata Mayfly Nymph Ephemerella mucronata Mayfly Nymph

Dorsal view of a Ephemerella mucronata (Ephemerellidae) Mayfly Nymph from the Yakima River in Washington

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.

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.

Do any of you fellows and gals own an Orvis Helios? I've been thinking of treating myself to a 9' #4 and would like opinions on action, is it a tip or mid flex rod, is the epoxy on the guide wraps first rate? how well is the overall finish of the rod compared to a Sage or T&T rod? Is the cork nice? Thanks.

have the 6WT mid-flex. they come tip flex too. love the mid-flex action 'cause it's not stiff or too fast. it's light and strong and caught many fine Labrador brookies. you could take a look in person to judge the finish; can't speak to that myself not owning the other brands you mention.

Hey Matt,

The Orvis H2 904 is offered in both a mid-flex and tip-flex. I would suggest you cast both to find which action suits both your casting and fishing best. The rods are made by Orvis in Manchester, VT and both the finish and components on these rods are first class.

Thanks for the info. Most of my rods are built on Gatti blanks. They are as fast as I would want. As many of you know while not a dry fly exclusive fisherman I do fish dry 90% of the time and want a fast rod to be able to make one false cast, two at the most, and put the fly back on to the water.

Maybe the fly fishing show in Lancaster, PA will have an Orvis dealer and I can try casting both the tip and mid flex rods.

Just happened to go to Ebay this afternoon and was looking for a gently used Helios 9' #4. Well lucky me I happened to see a new, never fished, with full warranty Orvis Helios 2 9' #4 being auctioned with no reserve. The auction had just 52 minutes left and I made a slight nudge to the starting price and sat at the fly tying desk until 2 minutes to the end of the auction. I was the only bidder and am now the owner of this Helios 2 9' #4 tip flex rod. Delivery due between 12/23 and 12/29.

Now I want to sell a gently used Sage Flight 9' #4 4 pc and a new Gatti 8' 6" #5 3 pc I built a few years ago that has never been fished. If anyone is interested in pictures and the particulars of the Gatti PM me.

I have a brand new 10' 4wt Helios 2 that I used up in the Sierras while tubing. I got mine while I was in san diego and bought a 5wt radian at the same time. They both are awesome but I prefer the Scott Radian. https://www.theflystop.com/scott-radian-review-fly-rod Either way you should email that shop. They gave me a giftcard for a bunch of free flies when I bought it
