Great Spreadwing (Archilestes grandis) is the largest species of damselfly in North America by total mass. This robust species prefers slow, wooded streams (Paulson, 2011) or sometimes small fishless ponds (B.C., pers. obs.). It occurs through much of Maryland, but is absent from the Eastern Shore (Richard Orr's Dragonflies and Damselflies of Maryland and District of Columbia).
There are 108 records in the project database.
