COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Olive Clubtail Stylurus olivaceus in Canada (2011)

    The Olive Clubtail is a dragonfly in the clubtail family. Adults are 56-60 mm long, have widely separated eyes and the tip of the abdomen, especially in males, is swollen; the wings are clear. The thorax is grey-green with broad, brown shoulder stripes and the black abdomen bears a yellow mark on the top of each segment and has yellow on the sides. The elongate larvae are distinguished by vestigial burrowing hooks on the tibiae (middle of front legs). All larval records of the Olive Clubtail in Canada are of exuviae (singular “exuvia”), the cast exoskeletons of the final larval stage, left on the shore after adult emergence.

Response Statements

  • Response Statement - Olive Clubtail (2011)

    This highly rare, stream-dwelling dragonfly with striking blue eyes is known from only 5 locations within three separate regions of British Columbia. It is restricted to small areas along warm lowland rivers, and infrequently lakes, where continuing decline in the quality of habitat is occurring. Threats include loss and disturbance of habitat due to human activity, such as beach recreation, impacts of invasive species of fish, invasive aquatic plants, and pollution by pesticides and fertilizing nutrients.
