Ants live in colonies where one or a few females, called queens, lay all the eggs. Most of the queens' offspring become worker ants that do not reproduce. A few are males, and some become new queens. Each queen ant can lay thousands of eggs per year.
Bees store their venom in a sac attached to their stinger and only female bees sting. That is because the stinger, called an ovipositor, is part of the female beeâs reproductive design. A queen bee uses her ovipositor to lay eggs as well as sting. Sterile females, also called worker bees, donât lay eggs. They just use their ovipositors to sting.
