Convention calls for the scientific name to appear in italics, for the genus to start with a capital letter, and for the species to start with a lower-case letter, as in Hexagenia limbata.

Yah but what do you know about Taxonomy???Convention calls for the scientific name to appear in italics, for the genus to start with a capital letter, and for the species to start with a lower-case letter, as in Hexagenia limbata.

Thanks for your input. I’m inclined to consider the Hex as a lake species. Taxon, Sculpin Swinger, and Cabezon are offering better possibilities without being able to examine a specimen.

Hexagenia limbata hatch from the Columbia River in the vicinity of Wanapum and Priest Rapids dams. Probably from the reservoirs rather than downstream of Priest Rapids.
Oh, no, you didn't....

The McKenzie has the same bug. Looks lovely but fish don't eat them, or so they say

I've only ever heard them called big yellow mayflies. Common in summer on west side rivers but never typically hatch in large numbers.

Touche - it has been a minute since my aquatic freshwater invertebrate class at the UW School of Fisheries...Convention calls for the scientific name to appear in italics, for the genus to start with a capital letter, and for the species to start with a lower-case letter, as in Hexagenia limbata.
