First 3-D reconstruction of copulation in Lepidoptera: interaction of genitalia in Tortrix viridana (Tortricidae).

Copulation process in Lepidoptera is studied for the first time with three-dimensional reconstructions of couples of Tortrix viridana, used as a model species. The internal genitalia is the scenario of multiple interactions between male and female, but the external remain static. A possible mechanism of stimulation of the female internal copulation organs is proposed.
