A study from the University of Sao Paulo published in the Journal of Insect Behavior describes the shocking behavior of coffee berry borers. These insects, which Discovery News calls "the most serious pests of coffee plants worldwide," have sex in coffee beans before they're roasted into the delicious drink.
The coffee berry borers are a type of beetle native to Africa. The females are just .07 inches long, and the males are about .06 inches long — tiny enough to get down inside coffee beans.
