June 12, 2022: with permission (thank you) meandered this prairie remnant looking for insects. One of the first sign of insects were galls on Horse nettles, Solanum carolinense; they were numerous. Collected 4 galls.
June 19, 2022: cut open a gall to a larva in a lightly woven cocoon
July 1, 2022: preparing to finally cut open another gall and a moth flew out of the rearing container. Cut open the 3rd gall to nothing, and the 4th gall to a dead moth, wings not expanded.

Batch rearing
