California Polytechnic State University, San Luis Obispo Plant Sciences Entomology Collection (CPSLO-PSEC)

Our collection has roughly 50,000 specimens, both pinned and in ethanol. The vast majority of insects have been collected by students here at the university, for varying entomology classes. Therefore, a large portion of the collection was collected from SLO county. However, many specimens are from around California, and we have a special Swanton Pacific Ranch collection. This collection is incredibly important to our school, as the Ranch is used by students of all disciplines to further their hand on education. Unfortunately, the Ranch burned in 2020, making these specimens invaluable.
