Physical Description
Diagnostic Description
This is the only odonate in northeastern North America with entirely black wings (Nikula et al., 2003). Smoky rubyspot (Hetaerina titia) is the only other damselfly that may have completely dark wings. It lacks the blue-green iridescence on the body and the wings are only about a fifth as wide as long. In sparkling jewelwing (Calopteryx dimidiata) only the apical fourth of the wings are black (Abbott, 2007). In the south-central U.S., smoky rubyspot, Hetaerina titia, is the only other damselfly that may have completely dark wings. It lacks the blue-green iridescence on the body, and the wings are only about 1/5 as wide as long. In sparkling jewelwing, C. dimidiata, only the apical 1/4 of the wings is black (Abbott, 2005).

Ecology
Habitat
Habitat Type: Freshwater
Comments: This species occurs in a variety of streams and small rivers but is most common along shallow forested streams. It tends to be found on smaller, more forested streams than the related river jewelwing, Calopteryx aequabilis (Nikula et al., 2003). Habitat generally consists of small, slow moving, canopy covered streams and occasionally exposed streams and rivulets. Nymphs are local in occurrence and restricted to slow creeks and quiet areas of running streams (Abbott, 2007).

Migration
Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Population Biology
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: > 300
Comments: It is common throughout Massachusetts (Nikula et al., 2003). In Maine it has been found in every county across the state (Brunelle and deMaynadier, 2005). It is found in streams across Minnesota (Haarstad, 1997). In the south-central U.S., it occurs in the Arkansas, Bayou Bartholomew, Brazos, Canadian, Cimarron, Colorado, Mississippi, Neches, Ouachita, Red, Sabine, San Jacinto, St. francis, Trinity, and White River watersheds (Abbott, 2005). It was recently found in Fort Sill, Lawton, Camanche Co. Oklahoma (Zuellig et al., 2006).

Life History and Behavior
Cyclicity
Comments: Adults perch on streamside and emergent vegetation with a few feet of the water. They fly low over the water or along forest paths in a bouncy, butterfly-like manner (Nikula et al., 2003).
Flight period in Louisiana is March 1 to October 31 (Abbott, 2005). Westfall and May (2006) documented flight period from February 7 (Florida) to December 3 (Florida). In Cape Cod, Massachusetts, it is June-September (Carpenter, 1991). In Kansas it is May to September (Beckemeyer and Higgins, 1998). In Georgia it is from late March to early November (Beaton, 2007). In Ohio it is from May 5 to September 22 (Glotzhober and McShaffrey, 2002). In the western Great Lakes, it is mid-May to early September (DuBois, 2005). In Massachusetts, it it mid-May to mid-September (Nikula et al., 2003).

Reproduction
Males are territorial and perform fluttering courtship displays for females. Females oviposit in floating, emergent or submergent vegetation, often with the male guarding nearby (Nikula et al., 2003). Males will vigorously compete among themselves for territories with submergent vegetation, the prime egg-laying habitat for females. Males attract females with a "cross display," where the male faces the female with his hindwings deflected downward at right angles to his body, and the forewings and abdomen are raised, revealing the ventral pale area of the abdomen. The major ity of mating and egg laying occurs in the early afternoon and a single male may guard multiple females, resulting in sometimes large congregations. Females will lay their eggs in submergent vegetation for 10 to 120 minutes and usually don't submerge themselves. The displays and behaviors of northern and southern populations may differ (Abbott, 2007). For a summary of these behaviors the reader is directed to Dunkle (1990).

Ebony Jewelwing
The Ebony Jewelwing (Calopteryx maculata) is a species of broad-winged damselflies. It is one out of the 170 species of the Odonata found in New England, the Mid-Atlantic states, and southeastern Canada.
Contents |
Identification
It is between 39–57 mm (1.5–2.2 in). The males have metallic blue-green bodies and black wings. Females have duller brown bodies and smoky wings and glistening white spots near tip wings. Naiad have pale brown bodies with darker markings.[1]
Habitat
It lives near wooded streams and rivers. Ebony Jewelwings flutter like a butterfly. When disturbed they fly a short distance to safety. These damselflies are easy to get close to as long as you approach slowly and don't make any sudden movements. They will often stop to rest on leaves or twigs. Ebony Jewelwings may fly far from water. They can be seen in the middle of the woods, while most damselflies and dragonflies are usually seen near ponds, lakes, or rivers.[2]
Breeding
Ebony Jewelwings mate in the summer. The male grabs the female behind her head with his tail or abdomen. After mating, females lay their eggs inside soft stems of water plants. Eggs hatch into larvae called naiads. Ebony Jewelwing naiads eat small aquatic insects. When the naiads are fully grown, they crawl out of the water and molt. They leave their old skin behind. The adult can soon fly off and look for a mate.[3]
Distribution
Its found throughout most of the United States (except 15 of the states) and southern Canada.
Flight season
This damselfly species is can be seen almost all year round in some regions. [4]
Prey
The Ebony Jewelwing has a wide variety of prey, including:[3] Asian Tiger Mosquito, Giant Willow Aphid, Fungus Gnat, Crane Fly, Large Diving Beetle, Eastern Dobsonfly, Water Flea, Green Darner, Aquatic Worm, Northern caddis fly, Rotifer, Copepod, Scud, Dogwood Borer, Six-spotted Tiger Beetle, Flatworm, and Green Hydra
Predators
The damselfly also has many predators, including:[3] Great Crested Flycatcher, American Robin, Big Brown Bat, Green Darner, Large Diving Beetle, Eastern Dobsonfly, Mallard, Eastern Painted Turtle, Bluegill, Largemouth Bass, Yellow Perch, Creek Chub, Channel Catfish, Red-winged Blackbird, Blue Jay, Common Snapping Turtle, Southern Leopard Frog, Common Carp, Common Water Strider, and Northern hogsucker
Shelter plants
The Ebony Jewelwing has many plants it uses for shelter. The following is list of plants.[3] Yellow Pond Lily, Hydrilla, Lizard's Tail, Green Algae, Pickerelweed, Common Cattail, Tussock Sedge, Greater Bladderwort, Common Duckweed, Black Willow, Spotted Jewelweed, Spotted Joe-pye Weed, Poison Ivy, Wild Grape[disambiguation needed], Sassafras, Greenbrier, and Buttonbush[disambiguation needed]
Relationship to humans
Like other damselflies they help people by eating large numbers of pesky insects, including mosquitoes, common houseflies, and other unwanted insects.[3]

Names and Taxonomy
Taxonomy
Comments: Subspecies C. m. floridana was described by Huggins (1927) based on Florida specimens. However, Byers (1930) concluded that naming subspecies was not feasible without further study (Westfall and May 2006).
