Rickera/Kogotus

[Mark Melton]

The reason this one is called Rickera/Kogotus is because they can't be differentiated as nymphs only as adults. So in areas where both are they are referred to as Rickera/Kogotus. They prefer fairly fast water. They're about 10-15 mm in length excluding the cerci and antennae. They're usually in the Russian River from late winter until mid-summer.

No, it's in the Perlodidae family.

No, it's in the Perlodidae family.

Hi Mark,
Great pictures. What do we know about their biology / ecology? I assume that they are predators, like most stoneflies. But on what? When do the adults emerge? Are these larvae more active at night at predators? Do just the adult females fly?

Steve,
A good place to start is the Gunnison County macroinvertebrate site. I've found a few papers (as well as the spot on the Gunnison website) that should give you a good start on the info you wanted.

Kogotus modestus (Plecoptera: Perlodidae) of Gunnison County, Colorado
