3) A colony of 150 big brown bats can protect local farmers from up to 18 million or more rootworms each summer.

4) The 20 million Mexican free-tails from Bracken Cave, Texas, eat 250 tons of insects nightly.

5) Tropical bats are key elements in rain forest ecosystems, which rely on them to pollinate flowers and disperse seeds for countless trees and shrubs.

6) In the wild, important agricultural plants, from bananas, bread- fruit and mangoes to cashew, dates and figs rely on bats for pollination and seed dispersal.

7) Tequila is produced from agave plants whose seed production drops to 1/3,000th of normal without bat pollinators.

8) Desert ecosystems rely on nectar-feeding bats as primary pollinators of giant cacti, including the famous organ pipe and saguaro of Arizona.

9) Bat droppings in caves support whole ecosystems of unique organisms, including bacteria useful in detoxifying wastes, improving detergents, and producing gasohol and antibiotics.
