The world's smallest winged insect is the Tanzanian parasitic wasp. It's smaller than the eye of a housefly.

When the pack kills an animal, the alpha pair always eats first. As food supply is often irregular for wolves, they will eat up to 1/5th of their own body weight at a time to make up for days of missed food.

There are approximately 2,700 different species of mosquitoes.
