California is home to four species of federally listed beetles. These species have been recognized by the US Fish and Wildlife Service as either threatened or endangered in their native habitats. In all cases, these species are restricted to areas that have been heavily impacted by human activities. The first two listed below are found only in the Santa Cruz mountains, and had historically small ranges, so were particularly susceptible to disturbance. The last two were probably once much more widespread in the Central Valley, but agricultural activities have greatly reduced the extent of their required habitats. Please follow the links below to read more detailed information about each of these species.
