Fireflies

The firefly is one of the flashiest bugs around. Each species of firefly has a special flicker code to attract mates of the same species. But male fireflies beware: not all female fireflies deserve glowing reviews. The female of one species of firefly has learned to imitate the moves of another. When a gullible male approaches, the firefly femme fatale captures and devours him. Some entomologists think its the sperm of the male firefly that triggers the urge in the female to eat the males of another species. A delightful snack for an already sexually satisfied female.
