"Occasionally, however, they are strangely attracted in groups to fresh paint on the sides of buildings during warm/hot weather! Speculation is that a volatile chemical in paint can mimic a certain attracting scent ("pheromone") which draws the beetles to each other. Some painters have returned from a lunch break only to find a number of them unfortunately dead in their open cans of paint. The Banded Alder Borer is the only known beetle that seems to display this potential attraction to freshly painted areas. "
