The black dots on the distribution map represent county records. The gold dot with crossbars
on the distribution map represents a record that was present on the original dot map but not in tblMain or the computer-generated map (see Notes).
Conocephalus occidentalis is found throughout California and on the west side of Oregon.

The distribution map on this page is referred to as the 2024 distribution map.
The records for this species are from tblMain and are in agreement with the computer-generated map and mostly in agreement with the original dot map. On the original dot map, there is an extra dot west of Toulumne, Mariposa, and Madera counties, probably representing Mono County. The original dot map was superimposed over the 2024 distribution map to locate the position for the gold dot with crossbars . On tblMain, the locality Reading was given for California but no county was given; Reading is in Shasta County. Shasta County was not on the original dot map or on the computer-generated map so this county was not added to the 2024 distribution map. [tmy 12 April 2025]
