A Key to Identification of Male Southwestern Darners
- BETA VERSION. Please email Kathy Biggs if you can suggest changes!

DARNERS - Aeshnidae


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
Neo-tropical Darners, Rhionaeschna* - 4 SW species
*New research in 2003 split these from the genus Aeshna
Mosaic &/or Neo-tropical 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
Pilot Darner Coryphaeschna- 1 SW species: large; green and dark abdomens
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. 134-135
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.
