COVER: An adult male Variable Darner (Aeshna interrupta) emerging on a Marsh Cinquefoil (Potentilla palustris) plant. The cast skin of the final-instar larva remains clinging to the plant above the dragonfly.The Variable Darner is one of the most common dragonflies in the rangeland ponds of the drier plateaus and valleys of southern British Columbia. Allover the province, it lives in sedgy ponds or lakes and, especially along the coast, around bog and fen pools. The common name comes from the shape of the lateral thoracic stripes of the male, which are usually very thin. These stripes are complete in most specimens from the Interior of the province, but are divided into spots (thus, interrupta) in coastal ones. The specimen was drawn by Rob Cannings.
