The slideshow and video above are based on Insects, Their Means and Ways of Living written by Robert Evans Snodgrass (1875-1962) in 1930, as well as an interview with Dr. Gene Kritsky published in Lloydiana in 2021. An American entomologist and artist, Snodgrass’ early interest in science and penchant for Darwin caused strife within his religious family and community. He went on to study zoology at Stanford University which introduced him to field work and research. During his career, he published six books, 76 scientific articles and received the Leidy Award from the Academy of Natural Sciences of Philadelphia in 1961.

The Theater of Insects
