...pg. 58
sizes: large, robust; fast; lengths: 56 - 116 mm
males: brilliant blue and/or green with brown
females: 2 or more forms, one like males; others green and/or yellow
instead of blue; brown and/or purple base
habitats: lakes, creeks, rivers; fields
behaviors: usually seen in flight; patrol waterways but also often
seen catching insects over fields; perch by hanging vertically; oviposit into
floating vegetation; some swarm; some migrate; when cool, blue coloration darkens
5 SW genera, including 18 species:
Mosaic Darners, Aeshna* -
10 SW species
*New research in 2003 split the genus Aeshna
Blue-eyed Darners, Rhionaeschna* -
4 SW species
*New research in 2003 split these from the genus Aeshna
Mosaic &/or Blue-eyed Darners, Aeshna/Rhionaeschna - large bluish eyes; mosaic
pattern; quite similar; upper appendages differ
Green Darners Anax - 2 SW species: large green eyes, both very similar except for Giant
Darner's much larger size; the Common Green Darner is known to be
a mass migrant
Malachite Darner Remartinia- 1 SW species: lime-green and brown
Riffle Darners Oplonaeschna- 1 SW species: top of segment 10 has a fingerlike projection

How to Identify Female Darners
example: female Blue-eyed Darner Rhionaeschna multicolor - non-male
like color form...pg. 59
To identify female Darners, use color of the line across face, presence (Rhionaeschna)
or lack (Aeshna) of a small bump under first segment, the presence
or lack of paired blue spots on abdomen underside, the presence and/or shape
of thoracic top and side stripes, and the ovipositor length. Use of an identification key is often necessary.
