Description
The waxy skin of the greater wax moth carries a changing chemical signature, and Mieczysława Boguś and Michalina Kazek chart how it shifts with sex and life stage. These moths plague beehives, and their surface lipids help them recognize mates and mark their stage of life. The team profiled fatty acids on pupae and adults with gas chromatography and mass spectrometry.
Male pupae carried eleven fatty acids and females thirteen, including two found only in females. As the moths matured, some acids vanished from the skin and others changed level. Adults regained a few lost acids and gained brand-new ones, including one unique to virgin males. Mating rewrote the profile again, raising some acids, lowering others, and shifting cholesterol opposite ways in the two sexes.
