Hex Mayflies
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.

Ever get tired of purchasing wing material? If you are like me, do you find that the package always seems to contain a limited amount of material and the color as well as structure is often not exactly what you want? But what if you could make wing material at a fraction of the cost, in the color and structure you want, that floats and is as tough as nails. Making this kind of wing material is a fairly simple process. To start you need the following items:

1. A pressing table
2. Iron (Hobby or regular pressing iron)
3. Scissors
4. Heat-n-Bond (which in a polypropylene or polyethylene product)
5. Netting or Polypropylene (PP) Hair
6. Polyethylene foam sheeting
7. Alcohol ink for additional coloring
8. Teflon Pressing Pad
