Insect watch album - Red Dragonfly

My observations about the Red Dragonfly is that when they are in abundance there must be some source of unpolluted running water in their immediate vicinity.  They can be watched along the small stream that meanders through the park for about half a kilometer length,  hugging on glass blades or dead twigs for a little rest then hunt for mosquitoes.  Their presence is a live litmus test that the stream water is unpolluted.  The mosquitoes thrive on the swampy grassland areas around the park.
