Insect sperm fight one another with brute force and chemical weapons.

When the sperm of different male insects meet inside a female, they use everything from wrestling to chemical warfare to try and fertilize as large a share of her eggs as possible, according to two studies published this week. The studies also show that females don’t just let the battle take its course, but manipulate it to their own ends.
