This topic is about the Saddle-case Maker Genus Glossosoma

The sporadic emergence of these caddisflies diminishes the importance of the freshly emerged adults and pupae, but they have unique periods of vulnerability as larvae during the day and again as diving egg layers at dusk that can make them very important. A taxon can only have one common name attached in the title but this is one of those genera whose species come in a variety of colors and descriptive common names. In the West their bodies generally come in tan to brown shades with matching wings, their wings can be speckled grayish tan or even almost black as with an eastern species. Some western rivers have astounding populations. See Glossosomatidae for more information. Read more...

Caught and photographed in the Upper Midwest on May 12, 2020. I resized my original photo for the website.

Jason, thanks.

I sent my two best original macro photos to an entomologist friend who believes they are Glossosoma intermedium or nigrior, which are common here.

I bet you can guess the river too, :-)

I hope all is well with you and your family. BTW, I still email back and forth with Frank P. and the new fishery manager quite often.

Stay safe!
