Editing Ghost moth (section)

==Predators==
Common predators of ghost moths include several species of bats and birds. These predators are attracted to the moths during the male flight displays. ''[[Northern bat|Eptesicus nilssonii]]'', the northern bat, has often been documented preying on lekking ghost moths. The ghost moth is a member of the family Hepialidae, an early branch of [[Lepidoptera]]. Species in the Hepialidae lack several predator defense systems, including [[ultrasonic hearing]].<ref name=":2" /> The ghost moth lacks sophisticated predator defense systems, and instead restricts its sexual behavior to a short period during dusk to reduce its predation risk. Despite these precautions, the moth is still at a large predation risk, especially at high latitudes where twilight is prolonged.

It is believed that the deaf moths, such as the family Hepialidae, pre-date the predatory bats that may have driven the evolution of ultrasonic hearing. It is currently believed that the ghost moth's restricted flight patterns and low flight positions may be their main form of anti-predator defense.<ref name=":2" /> The ghost moth displays for only 20–30 minutes at dusk, which aids in predator avoidance, as most bats typically do not start feeding until after dusk, and most birds stop feeding well in advance of sunset.<ref name=":1" />
