distribution Essentially just the eastern half of the Coastal Plain; absent from the western half of the Coastal Plain counties, including the Sandhills. Absent in the mountains and Piedmont, except for a record from Rutherford County. As would be expected from the NC range, this species' US range is mainly limited to tidal and estuarine areas, north to ME, though it does occur over most of peninsular FL. In addition, the OdonataCentral range map shows scattered records for TN, northeastern AL, and north-central GA; thus the collection record for Rutherford County may well be legitimate.
abundance Locally fairly common in coastal counties and those in the Tidewater zone, as there are several one-day counts of at least 30 individuals (plus an excellent count of 217 individuals from Hyde County). Rare to uncommon farther inland (such as in Bladen County).
flight The flight occurs from late April to late October. The Rutherford County record is for late July.
habitat Unusual for most damselflies -- mainly along the lower portions of large rivers near or at estuaries, including the vicinity of brackish marshes. Also at large lakes with sandy bottoms, such as Lake Waccamaw.
behavior Often perches low on emergent vegetation.
comments This species has a range in NC like no other damselfly, but quite a bit like several dragonflies, particularly Needham's Skimmer, Four-spotted Pennant, and Seaside Dragonlet. It is certainly one of the very few damselflies that can be locally numerous in coastal marshes and other wetlands along the coast. Though it is locally quite numerous, the fact that there hardly any recent records for the southern half of the coast suggests that the species should have a State Rank of S4 instead of the current S4S5.
