Behavioral videos:

The videos below are provided to illustrate different dragonfly behaviors that may be observed and recorded during Pond Watch or Migration Monitoring.

Dragonfly in Action - slow motion: Shows perching, takeoff and landing, individual wing movements.

Dragonfly Catching a Fruit Fly - slow motion: A clip from one of Stacey Combes videos, note the use of the legs to grab the pray and bring it to the mouthparts while in flight.

Dragonfly Eggs Hatching: Shows oviposition by tapping the abdomen on the water, followed by amazing close-ups of eggs developing and hatching into a prolarva, which molts almost immediately into a 1st instar nymph.

Dragonfly Larvae Hunting Backswimmers: Fantastic close-up that shows the operation of the rectal gills; full speed shots of strikes at prey and slow-motion replays showing labium extending; and some slightly gory footage of captured bugs being throuughly munched.

Dragonfly Laying Eggs in a Pond: Shows a female laying eggs by tapping the tip of her abdomen repeatedly against the surface of the water––a behavior that people sometimes confuse with drinking.

Dragonflies mating: Note that as the female lays her eggs in the water, the male follows and guards her to prevent any other males from mating with her. Also shows close-ups of tandom pair copulating in the wheel position.

Fascinating dragonfly in UltraSlow Flight: The ability of the dragonfly's 4 wings to each move independently of the others is seen clearly here.

Green Darner Dragonflies laying Eggs: Shows oviposition by inserting eggs in vegitation. The voiceover says that the male continues holding the female so he can pull her out of the water if she goes to deep, but in fact he is guarding her to be sure no other male can come along and mate with her before she has laid her eggs!

Adult emergence: A clip from Attenborough's "Life in the Undergrowth", with a fascinating step by step description of the adult emergence process.

Charles Anderson's Ted Talk: Describing his discovery of the migratory path of the Wandering Glider across the indean ocean.
