Enallagma hageni

Walsh, 1863

Dragonfly Page|Damselfly Page|Home Page


Hagen's Bluet is a small blue and black damsel that is very similar to the Marsh Bluet. The thorax of the male is mostly blue. Abdominal segments 6 and 7 are more black than blue. The female may be green, blue or tan, with an abdomen mostly black on top.

This is a northern transcontinental species with Nebraska at thesouthwestern edge of the range. It is widespread in the state and more common in the northern half. It is seldom found innumbers and is frequently back in the grass away from the water andfrom other more abundant species. It is easily confused with the much morenumerous Familiar Bluet and Tule Bluet, but this unlikely to account forthe limited number of records. It is strictly a pond species.
