Demonstration of Female Sex Pheromones and Adult Behaviour in Molanna angustata (Trichoptera: Molannidae)
Solem, John O.; Petersson, Erik
Sticky traps baited with extracts of whole bodies of females of Molanna angustata Curtis 1834 attracted significantly more males than the controls. This concluded that these extracts contained a female sex pheromone, which attracted males from a distance to places where receptive females were present. At these places, close to water, males of M. angustata also performed a swarming or courtship dance. Sequences in this dance are given. It was not possible to determine if females took part in this dance.
