COMMON GREEN DARNER (Anax junius)
- large size (length 3 inches, wingspread 4½ inches)
- long abdomen
- eyes dull greenish to bluish to brown
- thorax green
- abdomen blue in male, green in female, violet in immatures

Appears in North early in spring, before local dragonfly emergence, presumably migrants from south. Larvae develop through summer, emerge in July/August, then fly south. Breeding in South, tropics in fall/early winter. Those larvae develop through winter and emerge in spring, cycle repeats. There are also resident populations.
These all have green thorax, usually shining green or blue eyes; not known to migrate or occur in swarms.
