Spreadwings & Sprites
What are they?
Spreadwings and sprites usually rest with the wings held out at a swept-back angle - though sprites will often fold them along the back too. Most species lurk low in dense, pondside vegetation and some species can be found in woodland until they are mature.
Identification
Sprites are very similar to spreadwings but are noticeably much smaller. Identification of some species can be impossible without close checking of the external genitalia (the paraprocts and cerci) at the end of the abdomen.
Southern Spreadwing Lestes australis
Length: 1.7 inches. Flight time: Late April to Late September. The commonest and most widespread spreadwing in Cape May County. Formerly considered a subspecies of the Northern Spreadwing (Lestes disjunctus) but both are now considered to be separate species. Males can only be told from Sweetflag Spreadwing by the cerci, but females have shorter ovipositors than those of female Sweetflag Spreadwings.

Sweetflag Spreadwing Lestes forcipatus
Length: 1.7 inches. Flight time: Mid May to early November. A fairly common species but numbers can fluctuate and the species seems to be most common at well-vegetated vernal ponds during wet years. Numbers were noticeably high at Rio Grande in 2010 for example. Males can only be told from Southern Spreadwing by the paraprocts which are as long as the cerci (not shorter).

Swamp Spreadwing Lestes vigilax
Length: 1.7 inches. Flight time: Late May to mid September. A common species that often perches more conspicuously than other spreadwings and may be found in wooded areas away from water.

Elegant Spreadwing Lestes inaequalis
Length: 1.8 inches. Flight time: Late May to early August. A brightly-colored, metallic species which closely resembles Swamp Spreadwing, but has paler legs and the back of the head is pale cream-colored.

Slender Spreadwing Lestes rectangularis
Length: 1.7-2.0 inches. Flight time: Early May to late October. A widespread and fairly common species of well-vegetated ponds, especially in wooded areas. A distinctive species with its long, spindly abdomen.

Southern Sprite Nehalennia integricollis
Length: 0.8-1.0 inch. Flight time: Late June to early August. An uncommon species in Cape May County, though easily overlooked due to its small size. The pattern of blue on the tip of the abdomen should help to identify the male, while the female can be identified by the straight rear edge to the prothorax (the plate that sits between the head and thorax).

Sphagnum Sprite Nehalennia gracilis
Length: 1.1 inches. Flight time: Mid May to early September. A common species of well-vegetated ponds, acid bogs and ponds, though its small size makes it easy to miss.
