The ghost moth displays high levels of sexual [[dichromatism]] (see picture right). Female ghost moths are a yellow brownish color, while males have silver/white wings. It has been suggested that the difference in wing color between males and females is used for visual epidemic signaling.<ref name=":1" /> The upperside of males have un-pigmented scales with elaborate [[morphology (biology)|morphology]] and meshwork that allow for light reflection and may aid in attracting females.<ref name=":5">{{Cite journal|url=https://www.researchgate.net/publication/262048444 |title=Sexual dimorphism and geographical male polymorphism in the ghost moth Hepialus humuli (Lepidoptera: Hepialidae): Scale ultrastructure and evolutionary aspects (PDF Download Available)|journal=European Journal of Entomology|volume=106|issue=2|pages=303–313|language=en |access-date=2017-10-25|doi=10.14411/eje.2009.036|year=2009|last1=Kaaber|first1=Svend|last2=Kristensen|first2=Niels P.|last3=Simonsen|first3=Thomas J.|doi-access=free}}</ref> The females lack the intricate morphology of the males. The underside of both the male and female ghost moth is a uniform grey/brown color.<ref name=":5" /> It is believed that there is behavioral dimorphism as well, with one study showing that females were more attracted to light than males.<ref name=":7" />
