Status

Slender Bluet (Enallagma traviatum) is a widespread damselfly related to the more range-restricted Attenuated Bluet (E. daeckii) and Pale Bluet (E. pallidum). This species is found in a wide variety of ponds and lakes with vegetation, often with forest edges nearby (Lam, 2004).In Maryland, this damsel is widespread, but usually uncommon. Both the nominate subspecies and the western subspecies westfalli occur in Maryland, and they may be found in close proximity in the Catoctin Mts. (Richard Orr's Dragonflies and Damselflies of Maryland and the District of Columbia). Slender Bluet is ranked S3 (watch list) in Maryland.
