A small brown moth has one of the most complex sex lives in the insect world, new research has found.

The twilight courtship rituals of the gold swift moth (Phymatopus hecta) can be seen in summer from the British Isles to Japan.

John Turner, a biologist at England’s University of Leeds, said, “The love life of the gold swift moth is a veritable ‘Kama Sutra’ of mating patterns and positions. Colleagues have commented that this is the most elaborate mating procedure known in any insect, and I have certainly not observed anything to surpass it.”

There were so many courtship patterns that categorizing them became difficult. “I intervened on some occasions to stop the mating,” Turner said. “The insects would pause and then resume using a different pattern. It started to look a bit like a human courtship, with the moths doing it every which way and having a whole range of tactics for attracting a mate.”

The study, published in the Biological Journal of the Linnean Society , concludes that the complexity is evolutionarily stable and has probably persisted in the species for tens of thousands of years.

Because climate change affects some environmental factors like precipitation and temperature but not others like day length, phenotypic plasticity could allow some species to persist in a habitat despite changing conditions and provide more time for them to evolve and migrate.
