“…In K . gracilis the scent was shown to emanate from the hindwings and in W. copularis is known to be one of four detected volatiles (Allan, Jimenez‐Perez & Wang, ). In the absence of evidence to the contrary, this can be taken as applying to female fanning in P. hecta .…”

Leking moths present an evolutionary problem in their apparently simultaneous reversal of male-female attraction. The mating system of Phymatopus (or Hepialus) hecta embraces an unusually wide range of procedures. Both males and females use medium-range olfactory attractants (also probably visual signals), and both sexes will lure, and both will approach, the other, either when flying or perched. This produces an 'infinite variety' which includes the classic moth mating procedure (males fly to sessile female); a typical lek procedure (female flies to sessile male); a mating swarm (hovering male follows passing female); and intermediates such as a mutual courtship dance. Male behaviour includes a flying display, two sessile displays, and an escalating war of attrition. The system is versatile, persistent, and probably evolutionarily stable. The lek site has a high density of perches suitable for copulation which facilitate predator-escape by means of a dead drop. The whole supports a model for the evolution of resource-based leks which commence with a concentration of females on a hotspot, leading to a concentration of males; and then an escalating process of sexual selection as males become increasingly attractive over a distance to females, and females use the males as a way of locating the resource. The main stabilizing pressure may be selection for efficient mate acquisition, and as with grouse leking systems, the precondition for evolution was probably having travelling females that actively sought a reproductive resource or a predator free space.

The mating behaviour of Wiseana copularis was studied in the laboratory. In conditions simulating dusk, female moths began to fan their wings while remaining stationary. A Y-tube olfactory study revealed that wing-fanning females released a volatile sex pheromone that attracted males from a distance. Males spent significantly more time in the end of the Y-tube arm leading to a wing-fanning female than in the control arm. Males flew upwind in a zigzag flight and females stopped wing fanning immediately upon contact with arriving males. Mating lasted approximately 2 min, and mated females started ovipositing within minutes after mating. Males, but not females, later re-mated. Females laid between 450 and 1750 eggs over a 24-h period. Mating systems of W. copularis and other hepialid moths are discussed.
