Spatterdock Darner (Rhionaeschna mutata) is a beautiful, and frequently scarce northeastern and midwestern species found primarily at fishless ponds with water lilies (Nuphar sp.), especially spatterdock (Nuphar advena). Spatterdock Darner is active earlier in the year (about May-July) than similar species of darners. This dragonfly is highly state rare in Maryland (S1), and considered endangered in the state. While recorded from six counties, only five sites in three counties (three sites in Garrett, one in Washington, and one in Frederick Co.) are known to currently host breeding populations (Richard Orr's The Dragonflies and Damselflies of Maryland and the District of Columbia).
There are 48 records in the project database.
