Aphomia sociella

Male Aphomia sociella L, the bumble bee waxmoth, contains a sex pheromone in its wing gland, the major part of which is an R(-)mellein (= ochracin). The compound, which evokes searching behavior in females, is produced by a mold, Aspergillus ochraceus, found in the intestine of the last-instar larvae and in the bumble bee nest [180]. Apparently such insect-fungus relationships are widespread.
