Mayfly Species Baetisca obesa (Armored Mayfly)

Pictures Below
I have no experience with important fishing to this species, but it is probably the Baetisca species that Ernest Schwiebert discussed in Nymphs as locally abundant on one stretch of a Catskill river.

See the Baetisca genus page for more details.

Where & When

Regions: East, Midwest

This is the most common species of Baetisca in the East. Its official range extends into the Midwest, but populations there are overshadowed by the more prolific Baetisca laurentina.

I was fishing the Vermillion River in Minnesota south of the metro area and found a nymph similar to the Armored Mayfly Nymph. It did appear to be much more green in color. It was moving through a really muddy part of the stream, which I found interesting.
