Crimson-ringed Whiteface (Leucorrhinia glacialis)

The Whitefaces are small dark dragonflies with a white face and small dark patch at the base of the hindwings. Juveniles and adults have different colors, which further complicates an already-difficult-to-identify group. Five species occur in Wisconsin and are best separated by (1) patterns of wing venation, and (2) shape of the abdominal top spots, especially in females and juveniles. The Crimson-ringed Whiteface has (1) a white face, (2) bright and extensive red on the thorax (yellow in females), (3) a black abdomen, and (4) two rows of cells in the forewing's radial planate. Belted Whiteface has far less red on the thorax, a white base to the abdomen, and only a single row of cells on the forewing's radial planate. Male Hudsonian Whiteface (L. hudsonica) has red thorax but the abddomen has large, distinct red top spots. Crimson-ringeds are uncommon in Wisconsin, often occurring at bog ponds/lakes in the northern part of the state. I saw individuals at just a couple of sites in 2008.
