showing the body parts

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 underside at the end of their abdomen and only two terminal abdominal appendages.
Damselflies lay their eggs directly into vegetation.
The SW has 16 genera representing all 5 North American families:
1. Pond Damsels - Coenagrionidae
2. Shadowdamsels - Platysticidae
3. Spreadwings - Lestidae
4. Broad-winged Damsels - Calopterygidae
5. Thread-tailed Damsels - Protoneuridae New 2016

Directions: Click on the image that looks the most like the damselfly you want to learn more about, or just scroll down the page for the pond damsels, which are the most common.

Damselflies are arranged within family by predominant color within genus. There are 2 pages of damselfly images. Pond Damsels continue on this page. Damselflies in the other families are on a second page.

Pond Damsels: Coenagrionidae


sizes: small to medium; lengths: 20 - 50 mm
males: usually blue and black, a few red, yellow or violet;
varying degrees of light and dark colors on abdomens;
clear wings held alongside or over the abdomen when perched, small stigmas
females: abdomen more cylindrical; most tan but some blue or grey/brown or peachy
habitats: quite variable, but usually still waters or quiet streams
behaviors: wings held closed when perched; low flying
10 SW genera, totaling 63 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 lavender & 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 Damsel, Apanisagrion: thin, long abdomen; coloring dark and pale; dense venation on lower margins of wings
6. Red Damsels, Amphiagrion: mostly red abdomen with black thorax; 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 updated at least annually and are based on Western maps originally created by Dennis Paulson (pre-2007)

Bluets are arranged by similarity in markings.

female Bluet - malelike color form
GENUS: Enallagma The American Bluets - 16 SW species

description: males are usually bright blue & black patterned; but a few in other states show yellow/orange;
very similar in appearance to Dancers but flight not `dance-like';
wings are held folded alongside the body, not sail-like over the back as in Dancers;
leg hairs not twice as long as space between them;
eyes 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

Black-fronted Forktail Ischnura denticollis

size: very small, length 22 - 26 mm

male: no stripes or dots top of thorax; all dark above, sides of thorax blue (green in immature); blue patches on top & bottom segments 8-9 do not touch; chartreuse underside; stigma has white margin at rear; frail; top appendages bent down. SF Forktail, rare, CA's Bay Area, lower appendages not as hooked/noticeable

similar species: the very rare San Francisco Forktail is the 'twin' to the Black Fronted, but has differently shaped appendages; lacks the white margin at the rear of the stigma: all 'Black-fronted' type forktails in the Bay Area that appear to not have this stigma should be examined in hand. The two species have been known to hybridize.

female: immature - pale coral; mature green/blue thorax sides

habitat: lakes, ponds, seeps

SW flight period: all year in south

SW distribution: all Southwest

male: thorax top and abdomen dark; blue spots on segments 8 and 9; underside chartreuse; appendages up-pointing

female: cryptic brown, reddish, or male-like

similar species: very similar to Black-fronted Forktail, hence the Latin name `gemina' for twin; SF Forktail is slightly more robust; compare the two by appendages; SF Forktail lacks white margin at rear of stigma; eye spots back of head are more circular in shape than Western's, Mexican's, Eastern's or Pacific's

SW habitat: weedy ditches; often near salt water

SW flight period: March 8 - November 6

SW distribution: CA endemic; S.F. Bay Area; Santa Cruz (historical); rare: PLEASE REPORT ALL SIGHTINGS

Swift Forktail Ischnura erratica

size: medium, 29 - 34 mm

male: blue stripes on top of thorax with black in center; larger than most other forktails with bolder markings; yellow under abdomen with thin yellow rings; blue on thorax sides is similar in shape to blue on sides of Bluets; blue on sides has a dark line coming in from the back at mid-height; dark abdomen has blue spots top of segments # 8 - 9; lower appendages are much longer than uppers; long enough to see thru binoculars; stigma bi-colored

female: abdomen top all dark, with dark green thorax sides, eye spots, and thoracic side stripes; or colored like male;

similar species: larger than other similarly dark Forktail species; continuous blue side stripe, not the !! of the similarly sized Exclamation Damsel; Western Forktails are much smaller and have a much more prominent blue line between the post-ocular eye spots; use appendages to differentiate

SW habitat: ponds and creeks

SW flight period: February 24 - September 17
