	DARNERS - Aeshnidae sizes: large, robust; fast; lengths: 56 - 116 mm 5 SW genera, including 18 species: Mosaic Darners, Aeshna* - 10 SW species New research in 2003 split the genus Aeshna* Tropical/Blue-eyed Darners, Rhionaeschna* - 4 SW species New research in 2003 split these from the genus Aeshna* Green Darners Anax - 2 SW species [no common genus name?] Darners Remartinia- 1 SW species Riffle Darners Oplonaeschna- 1 SW species 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 Mosaic or Blue-eyed/Tropical Darners, Aeshna/Rhionaeschna - large bluish eyes; mosaic pattern; quite similar; upper appendages differ Green Darners, Anax - 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
Photos Darner exuvia The exoskeleton left behind when a darner nymph metamorphoses to become a flier.	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.
