Status
Ocellated Darner (Boyeria grafiana) is the more range-restricted of our two Boyeria species (Fawn Darner is the other one). This subtly beautiful dragonfly inhabits streams and rivers, similar to Fawn Darner, but with a marked preference for rockier substrate. The two species can often be found on the same streams. The grayer coloration and more prominent pale markings of Ocellated can sometimes be used to tell it in flight from the drabber brown Fawn Darner. They also differ in patrolling behavior of the males, with Ocellated usually flying faster, and less inquisitively than Fawn. Ocellated lacks dark basal markings on the wings, which Fawn Darner shows (Paulson, 2011). This species is mostly northern, and in Maryland, it appears to be restricted to Garrett, Allegany, and Washington Counties (Richard Orr's The Dragonflies and Damselflies of Maryland and the District of Columbia). At some sites, at the proper time and season, it can even be numerous (Jim Brighton, pers. comm.).
