Field/Photo key to Darners
|
Family: DARNERS - Aeshnidae
4 CA genera, including 11 species:
sizes: large, robust; fast; lengths: 56 - 111 mm
males: large eyes, bodies brilliant blue and/or green with brown
females: many color forms, most showing green and/or yellow instead of blue, with a background of brown and/or purple, others like male, ovipositor under tail base
habitats: breed in lakes, creeks, rivers; feed over fields
behaviors: usually seen in flight; patrol waterways but also often
seen catching insects over fields; perch by hanging vertically; most solo oviposit into
floating vegetation; some swarm; some migrate; blue coloration darkens when cool
distribution: found throughout the state, at all altitudes
Green Darners Anax - robust, large green eyes meet in center, forms a seam, thorax solid green,
abdomen more solidly colored, wings mostly clear but may be yellow-tinged, some are migratory - 2 CA species
Mosaic Darners, Aeshna* - large blue eyes meet in the center, form a seam,
mosaic patterned abdomen, difficult to distinguish to species without catching them (in net or digitally) - 4 CA species:
*Research in 2003 split the genus Aeshna
Neotropical/Blue-eyed Darners, Rhionaeschna* - like Mosaic Darners,
but having a small bump under the 1st segment - 3 CA species
Riffle Darners Oplonaeschna - RARE - very similar to Mosaic darners; top of segment 10 has a fingerlike projection - 1 CA species
nymph - long and slender, crawl about on underwater vegetation

female Darner and exuvia
The exuvia is the exoskeleton left behind
when a darner nymph metamorphoses into a flier.
|
How to Identify Female Darners
example: female Blue-eyed Darner Rhionaeschna multicolor - non-male-like color form
female Darners have only 2 appendages; each species has several color forms; 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.
