Caption
Researchers analyzed the relative abundance of eight species of bumble bees in the US. Black areas of the US. map represent the historic range of Bombus affinis, one of the species found to be in decline. Yellow circles indicate the total number of bumble bee specimens collected at a given site. Orange areas in the circles represent the relative proportion of B. affinis specimens found at that location. (Yellow circles with no orange regions indicate no B. affinis specimens were found at that location.)
