Common Name: Lancet Clubtail dragonfly (male)

Comments: Male lancet clubtails have claspers at the end of the abdomen, which females lack. Lancet clubtails are common in Massachusetts near slow streams and ponds.

The name lancet comes from the dagger-shaped marking on the abdomen. The
clubtail moniker comes from the swelling of the posterior abdomen (males only).
