What does the name mean?

Frenatae is named after a suborder of Lepidoptera that was proposed by John H. Comstock (1849 – 1931) at the end of the 19th Century. His division was based on the way the fore and hind wings were connected, in the case of Frenatae, by a frenulum. 

The legacy of Frenatae began in 1915 and was established by Professor Arthur G. Ruggles (1875 – 1947) who played a dual role both as University Professor and State Entomologist, starting at the University in 1902 as Assistant Entomologist at the State Experiment Station. Historically the club met every Monday for several decades before it was deemed more fitting to meet with less regularity, but has always been run and managed by graduate students at the University.
