Description: 2-Methylhexacosane is a saturated hydrocarbon and an insect pheromone. It has been found in the cuticle of M. dasystomus females, but not males, where it contributes to the mating behavior of males, as well as in D. melanogaster females where it modulates aggression of males towards females. 2-methylhexacosane has also been found in yellow jacket trail extracts.
