Sketch of a damselfly
showing the body parts ...pg. 90
by Barbara Chasteen

DAMSELFLIES - Zygoptera


Slender-bodied, generally smaller and more frail than dragonflies. Most have an eyespot in back of each eye.
When perched, all four wings are usually held together alongside or sail-like over the abdomen.
Eyes set far apart on head, appear hammer headed.
Weak fliers, usually found not too far from water.
males have a bump (genitalia) under their 2nd abdominal segment and four terminal abdominal appendages.
Females have a wide ovipositor on the lower end of their abdomen and only two terminal abdominal appendages.
Damselflies lay their eggs directly into vegetation.
15 SW genera representing 4 of the 5 American families:
1. Pond Damsels - Coenagrionidae
2. Shadowdamsels - Platysticidae
3. Spreadwings - Lestidae
4. Broad-winged Damsels - Calopterygidae


Shadowdamsels - Platysticidae

Pond Damsels: Coenagrionidae


sizes: small to medium; lengths: 20 - 50 mm
males: usually blue and black, a few red, yellow, violet; varying degrees of blue on abdomens; clear wings held alongside or over abdomen when perched, small stigmas
females: abdomen more cylindrical; most tan but some blue
habitats: quite variable, still waters, quiet streams
behaviors: wings held closed when perched; low flying
10 SW genera, totaling 56 species:
1.
American Bluets, Enallagma: most are blue & black patterned; perch on vegetation; wings at rest are held alongside abdomen; tandem oviposit at still water sites
2.Eurasian Bluets, Coenagrion: similar to American Bluets, showing more black
3. Dancers, Argia: most are blue & black patterned, some are lavendar & black, "dancing" flight; perch on ground and/or rocks with wings held closed above abdomen; tandem oviposit in moving waters; territorial wing clapping; long spines on legs
4.Painted Damsel, Hesperagrion: one species; red eyespots & 'tail'
5. Black & White Damsels, Apanisagrion: dark and pale coloring; dense venation on lower margins of wings
6. Red Damsels, Amphiagrion: black and red coloring; small but stocky
7. Firetails, Telebasis: red coloring; small & petite
8. Exclamation Damsel, Zoniagrion: one species; similar to forktails; 2 blue exclamation-like marks top of thorax
9. Forktails, Ischnura: mostly black; blue on thorax & near abdomen tip; perch on emergent vegetation; nontandem oviposit into floating vegetation; resting wing position variable
10. Sprites Nehalennia: metallic green coloration; small & petite

Southwestern distribution maps are based on Western maps originally maintained by Dennis Paulson (pre-2007)

female Bluet - malelike color form
GENUS: Enallagma The American Bluets - 15 SW species ..pg. 91

description: males are usually bright blue & black patterned; but a few show yellow/orange;
very similar in appearance to Dancers but flight not `dance-like';
wings are held folded down alongside the body, not sail-like over the back as in Dancers;
leg hairs not twice as long as space between them;
eyes often quite black on top unlike dancers which are more often a dark blue color;
the black line on side of thorax often makes a 'jag' or 'elbow' near the head;
females: several color forms: usually tan or gray where male is blue; sometimes colored male-like but usually with much less blue;
have a vulvar spine on segment 8 which Dancers lack
behavior: fly low over the water & grasses along shore;
perch on vegetation with wings slightly drooping at abdomen side;
tandem oviposit at still water sites;
can form swarms over water while ovipositing
habitat: still water with abundant vegetation

habitats: ponds, marshes, streams, slow rivers
behaviors: often hold wings open when at rest, la stealth bombers; oviposit in plant tissue that is above water level
Pond Spreadwings, Lestes: found flying at still water sites summer through fall; patrol shoreline from emergent vegetation on which they rest; oviposit while in tandem into non-woody vegetation above the water level
Stream Spreadwings, Archilestes: moving water sites; SW's largest damselflies; tandem oviposit into woody vegetation such as bay, alder & willow branches overhanging creeks/small rivers (even when dry); late season flight
