Here is more info.

When Generu Serutasu uses her pheromones, she doesn't just use them for mating, she also uses them as beacons to attract Aruserutasu when she needs help against danger or when she can't find food or when she wants food. When Aruserutasu pick up the scent of the Generu Serutasu, the first and only thing they think about is a mate but, if the Generu Serutasu uses a large amount of enegry while fighting of a threat and that male is with her, she'll eat him to regain her enegry but, atleast when she eats the male, she gains some of his sperm.

She also can shoot the pheromones on an organism to send the Aruserutasu on mating overdrive and, attacking and trying to mate with another monster while Generu Serutasu makes her escape.

Some Aruserutasu are smart and either mate with her while she is eating another Aruserutasu or just bring a decent sized kill with them for her to feast on while they mate with her, which they have to do fast before she finishs her meal and goes to the next course if she is still hungry.

Also, it seems Generu Serutasu live longer than Aruserutasu, which really isn't to surprising.
