Other: The River Jewelwing is the largest damselfly in Alberta. The males have distinctive dark wingtips and a bright green body.  Female Jewelwings have a small white patch on the tip of their wings (pterostigma) and may have smoky colored wings.  These damselflies are found along small forest streams and rivers.  Originally believed to be a northeastern Alberta species with a few isolated southern populations, it has now been found as far south as Water Valley along the Little Red Deer River and along the Milk River near the US/Canada Border.
