Brown Recluse does not occur in California
Despite ongoing claims by the general public, and in some cases medical practitioners, the brown recluse spider does not occur in California. Many years of searching for the spider, including public offerings of rewards, have failed to find the spider in the wild there.
A few specimens have been collected (about 40) in the 100+ years of scientific collecting in California, but they have ALL been associated with boxes or similar items that were recently shipped from locations where the spider occurs.
