Document Summary
Swarms of male midges form and wait for females to fly in, upon which they dance, and the female chooses the best dancer. Female ebony jewelwing (damselflies) have white spots on the end of their wings and flap their wings rapidly to notify a nearby male of acceptance or open up their wings flat to notify a nearby male of rejection. Male ebony jewelwing sperm is produced in a holding chamber near their head. They have a pinsir used to hold the female during courtship and used to put their sperm in the female, as well as removing any existing male"s sperm. Fireflies use aerial light display and flash their light in a specific pattern to find potential females. Synchronized displays are displays where both the male and female participate. Swans perform mutual displays, doing series of actions together at the same time. Sandhill cranes perform ritualized dances, taking turns bowing and jumping.
