Editing Ghost moth (section)

====Pheromones====
Males perform a flight display and use both chemical and visual signals to attract females to their mating sites.<ref name=":7">{{Cite journal|last=Mallet|first=James|date=1984-01-01 |title=Sex roles in the ghost moth Hepialus humuli (L.) and a review of mating in the Hepialidae (Lepidoptera)|journal=Zoological Journal of the Linnean Society|language=en|volume=80|issue=1|pages=67–82|doi=10.1111/j.1096-3642.1984.tb02320.x|issn=1096-3642}}</ref> While aggregating in leks, male ghost swifts use [[pheromones]]..

The olfactory substances used to attract females are produced on the male's hind tibial brushes, and were said to be "goat-like", meaning the smell of the [[Goat Moth]] caterpillar.<ref name=":7" /><ref>R South 1909.
