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 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.

Time to get everyone into the tying mood. Here one of my new ones to get everyone started.



Cinabar Flymph

Hook: Daiichi #1550 #12
Thread: Orange Uni-thread
Hackle: Golden Speckled Hen Back-one side stripped off of fibers.
First Ribbing:One strand of Peacock herl
Second Ribbing: Fine copper wire counter-wrapped.
Body:Cinnamon colored bear underfur mixed with a little Hare's Mask of the same color. The body was dubbed on 6/0 Danville Tying thread of Pale orange color Leisenring fashion. When dubbing, the fibers of fur were laid perpendicular to the tying thread.

Nice! Very pretty fly.

I'm about to get tying here soon. What psyches me up is bug sampling on my home streams, (breaking some ice to do it), which has me thinking about designs to add to the list. First, I have a new fly rod to finish though.

Mark,

I'm heading up tomorrow towards Lansing for a FFF Fly Tying Expo to try and kick start my winter tying...I have been really dragging it. Taking my 12 year old nephew Jacob with me to see what he thinks...We are going to walk some trails after to see if we can spot any winter birds of interest.

Also, re-signed up today for a tying group I belong to that ties through the winter months from Jan-Mar...It's run at a middle school by the Challenge Chapt of TU.

I guess you are our cheer leader Mark, now lets get tying boys! It will be Opening Day in a blink.

Nice fly as usual Obi Wan of the Softhackle...:)
