... that they use to grasp females securely during mating, acting like a vice grip; these legs do not enhance performance during take-off relative to females. Oedemera nobilis Jumping Mating Locomotion High-speed imaging Large hind legs are frequently an indicator that jumping is a notable...

... affected by such bacterial infections because of their mating ecology. In both sexes, mating is restricted to a short window early in the adult stage; there are no further chances to mate later in life. Males die shortly after mating, but queens use the acquired sperm to fertilise their eggs for years...

...Andreas Simon Brandstaetter; Florian Bastin; Jean-Christophe Sandoz During the mating season, honeybee males, the drones, gather in congregation areas 10–40 m above ground. When a receptive female, a queen, enters the congregation, drones are attracted to her by queen-produced pheromones and visual...

...Romina B. Barrozo; Christophe Gadenne; Sylvia Anton SUMMARY In the moth, Agrotis ipsilon , newly mated males cease to be attracted to the female-produced sex pheromone, preventing them from re-mating until the next night, by which time they would have refilled their reproductive glands...

...Benjamin Houot; Nicolas Svetec; Raùl Godoy-Herrera; Jean-François Ferveur SUMMARY The natural variation of sex-specific characters between populations can favor their behavioral isolation, eventually leading to the formation of new species. Marked variations for male courtship, mating...

...Romina B. Barrozo; David Jarriault; Xenia Simeone; Cyril Gaertner; Christophe Gadenne; Sylvia Anton SUMMARY In the male moth, Agrotis ipsilon , mating induces a transient inhibition of behavioural and central nervous responses to sex pheromone. Newly mated males are not attracted to sex pheromone...
