Sold on the Salvia
Ever watched Valley carpenter bees (Xylocopa varipuncta) foraging on salvia? Native pollinator specialist Robbin Thorp, distinguished professor of entomology at the University of California, Davis, recently noticed a flurry of carpenter bees in the grape-scented sage, Salvia melissodora, in the...
