Dragonflies at Perch Creek:

Dragonflies and Damselflies have developed from ancestors originating at least 300 million years ago! There has been relatively little change in body design from those in fossil records. (The Dragonflies and Damselflies of Algonquin Park, Colin D. Jones, et al 2013.)

The Eastern Pondhawk can be found around Lakes, ponds and slow streams. It is a voracious species that catches large insects, including its own species! (The Dragonflies and Damselflies of Algonquin Park, Colin D. Jones, et al 2013.)

Jewelwings are among the largest dragonflies in Ontario with "metallic" body colouration and dark wings. The Ebony Jewelwing female is in the top photo and is identifiable by the white dot on her wings.

The Common Whitetail tends to have a broader body than many other dragonflies.

A female Widow Skimmer seems to be hiding from me! When the legs are held 

together, the leg hairs act like a net and help dragonflies capture insects while in flight.

Although the front of the white face isn't visible in the photo, this creature is well named. It is called a Dot-tailed Whiteface! The yellow dot on the tail also helps in identifying the species.
