Abstract


Effective island conservation depends on thorough biodiversity surveys and species assessment. The U.S. Fish and Wildlife Service in coordination with Point Blue Conservation Science undertook a two-year insect survey of the Farallon Islands, California, in order to catalog current insect and spider species on the island and to gather information that will be used to examine prey dynamics to aid in the conservation of the endemic salamander Aneides lugubris (Hallowell). The report lists 11 insect orders representing 60 families, 107 genera and 112 insect species on Southeast Farallon Island. Holometabolous orders were the most represented on the island with Coleoptera and Diptera being the most abundant, followed by Lepidoptera and Diptera. One spider order was identified, representing six genera and six species.
