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

behaviors: wings held closed when perched; low flying
10 SW genera, totaling 62 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

forktails; 2 blue exclamation-like marks top of thorax
9. Forktails, Ischnura: mostly black; blue on thorax

GENUS: Enallagma The American Bluets - 16 SW species ...pg. 91
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...pg. 125
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

San Francisco Forktail
Ischnura gemina...pg. 125
size: small, length 24 - 28 mm; wingspan ~28 mm
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...pg. 158 & inside back cover dust jacket
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
