Occurrence
Several species of bees (such as some of genera Colletes, Halictus, Lasioglossum) and butterflies (such as some of genus Heliconius) use octadecanolide as a pheromone.[1] The Dufour's gland of bees in the Halictinae subfamily, contains octadecanolide along with other macrocyclic lactones, which could be used for a range of different applications like nest building, larval food and chemical communication.[2][3][4]
