DISTRIBUTION AND HABITAT

This species inhabits shallow acidic Coastal Plain ponds with muddy substrates and ample vegetation. It also occurs along the shallow, muddy fringes of large lakes. The New Jersey Pine Barrens region may be the center of abundance for this species. It is often the most abundant damselfly present. Pine Barrens bluets have been found in most Coastal Plain counties.

DIET

Nymphs feed on aquatic invertebrate; adults on flying insects.

LIFE CYCLE

Pine Barrens bluets have an early and brief flight season. They can be observed from early May through late June. They are one of the first damselflies encountered during the year.

CURRENT STATUS, THREATS, AND CONSERVATION

Although common in New Jersey, this species is rare from a global perspective. Its entire range lies within a region undergoing severe development pressure. Habitat degradation and lowering of water tables are primary threats. Destruction of surrounding uplands and fields deprives newly emerged adults of protection from predation and adverse weather. For these reasons, this is considered a Special Concern species in New Jersey.
