A genus of primitive moths known as ghost moths or swift moths, with simple wing structure and distinctive mating behavior.
From Greek 'hepios' (creeping, from the appearance of their caterpillars) + '-alus' (genus suffix). The scientific name refers to their larval stage.
Male Hepialus moths perform incredible hovering dances while holding their wings in a tent-like position, and females navigate toward them by sight—it's a mating ritual that hasn't changed in millions of years.
