The Butterfly Fauna of Two Adjacent Plant Communities in the Sierra Nevada Foothills of Mariposa County, California
A butterfly fauna encompassing two plant communities in the Sierra Nevada foothills was surveyed and was found to contain 59 resident and 35 non- resident species. 63% of the residents but just 3% of the non-residents are uni- voltine, and only 44% of the resident species are shared by both plant commu- nities. Dispersal between them by residents normally found in only one of the plant communities rarely occurs. Information on climate, relative abundance, flight season, dispersal, behavior, and bionomics are presented. Based upon pa- leobotany inferences, butterfly species endemic to the Foothill Woodland are pre- Pleistocene, whereas the Yellow Pine Forest endemic subspecies are post-Pleis- tocene (Holocene).
