The California dancer (Argia agrioides) flies from April until as late as early December. This common damselfly can often be found perching on rocks or the ground – usually near moving water.
California dancer males are vivid blue with black markings. The thoracic shoulder stripe is forked, the second abdominal segment has a stripe and the eighth through tenth abdominal segments are blue. Females can resemble males with less vivid colors or can be tan and black.
This California dancer was photographed along the spillway between Crystal and Baum Lakes (Shasta County CA).
