Sex pheromone for an Emperor

I made a rookie research error. Saturnia pavonia, the Emperor Moth, was previously known as Pavonia pavonia, and in my search for the chemical identity of its sex pheromone (which is in the moth lure I mentioned previously) I’d assumed these were its only names. But, apparently, it was also known as Eudia pavonia.

Once I’d realised this, a scientific literature search quickly found a paper discussing the moth’s sex pheromone: (Z)-6,(Z)-11-hexadecadien-1-yl acetate. This is closely related to another chemical gossyplure, a 1:1 mixture of the (Z,E) and (Z,Z) isomers of hexadeca-7,11-dien-1-yl-acetate. That chemical is used commercially to lure cotton-infesting moths to traps to reduce breeding of different species Pectinophora gossypiella.

So, with the systematic name, I could get the InChI string from one converter and then generate a chemical structure, so here it is together with the male moth I photographed, which is attracted to this chemical:
