Courtship of the Flies

Caption

The male fruit fly approaches the female (A), tracks her (B), and extends a wing (C) to produce a species-specific song. He curls his abdomen a full 180-degrees (D). If the female is receptive, they mate. The doublesex and fruitless genes help determine this courtship behavior.
