Mating systems in primitive Lepidoptera, with emphasis on the reproductive behaviour of Korscheltellus gracilis (Hepialidae)

Adults of Korscheltellus gracilis (Grote) are crepuscular. Flight is restricted to two 20–40 minute periods each day: the first flight follows sunset during evening twilight, the other precedes dawn. Four to five times as many adults are active during the evening when courtship, mating and oviposition occur. Of these behaviours, only oviposition occurs during the pre-dawn period of activity. Field observations indicate that females release a sex pheromone while fanning their wings. Females usually fly before pairing. There is no obvious female choice or stereotyped courtship behaviour prior to pairing.
In some hepialid genera females attract males, while in others ( Hepialus Fabricius, Phymatopus Wallengren, Sthenopis Packard and Zenophassus Tindale) the calling system is reversed, with males attracting females. Cladistic analysis of the Hepialidae suggests that the plesiomorphic condition for the family is for females to release the long-distance attractant, and that the reversed calling system represents a derived condition restricted to lineages within a single clade.
Available information on the mating systems of other basal lepidopteran lineages and Trichoptera support the hypothesis that ancestral Lepidoptera possessed a female-released, long-range attractant. Support for this position comes from (1) published literature; (2) field observations made by DLW; (3) the apparent absence of male scent structures and recognizable male calling behaviour among the pre-Neolepidoptera; and (4) cases of male antennal elaboration in several basal lepidopteran lineages.
