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.

Tim,
If you happen to see this log on...I've sent you a private message and you can only see it if you are logged on. I see that you have only logged on once way back in July of 2008, but maybe you will see this by chance and get to read my message.
For those of you that might see this message Tim Neal is one of the better fly tiers in Michigan and has tied for decades...He ties and carries the flame for the old Au Sable flies...Traditional flies famous around the river...The Harris Special, Robert's Yellow Drake, Borchers, the Madsen Skunk, and the old Barber Pole, etc...One day we will get Tim and his buddy JR, also of Grayling, to publish a book with these famous patterns and their histories.
