Clamp-tipped Emerald (Somatochlora tenebrosa) is a widespread and familiar Somatochlora in much of the east. It is named for the extremely peculiar, clamp-shaped cerci and epiproct of the male. This dragonfly breeds in small, shaded forest streams (Paulson, 2011). In Maryland, the species is widespread, and is probably the most common species of its genus in the state (Richard Orr's The Dragonflies and Damselflies of Maryland and the District of Columbia).
