This paper summarizes the findings of my study (1977-1982) of the presence and phenology of moths in the genus Catocala at the UWM Field Station. Use of sugar bait and black light traps resulted in the capture of 19 species. This report includes a phenological list of the specimens and line drawings of each, depicting size and hindwing coloration.
