They thrive and breed quickly at temperatures above 17oC, the adults disperse by flight and the earlier stages are transported with host products and so they may colonize and spread quickly, the only requirements seem to be moderately high temperatures and at least some humidity. As larvae mature, they become crescent-shaped and their mobility decreases.
