Some species of termite queens can lay 40,000 eggs a day!

Brunneria floridana, a species of Praying mantis, consists only of women. There are no men in this insect family.

Some walking sticks consist of only females and reproduce parthenogenetically, that is, without males. 

Only female bees, wasps and ants can sting. This is because the sting is a modified egg-laying organ called an ovipositor. 

Only female mosquitoes, horse flies, black flies and biting midges bite. They need blood in order to produce eggs. On the other hand, males feed on nectar. Females also take nectar and other plant fluids as food. 

There are certain mosquitoes that are autogenous and don’t require blood at all for egg production. 

There are species of fireflies (lightening bugs) called femme fatales. In these species, the females mimics the flash patterns of other species’ of firefly males in order to lure them to them so they can eat them.
