Species are shown alphabetically within taxonomic level. My photos of butterflies and moths are on a separate page, as are my photos of other insects. If you see an error, please let me know via the contact tab at the top of the page.
Gomphidae: Russet-tipped Clubtail (Stylurus plagiatus)
This species has the habit of hanging vertically off the tips or edges of leaves. I'm calling this example an immature female because the mature females have blue eyes. The males have pronounced "clubs" at the ends of their abdomens, but on the females this feature is almost absent.
Libellulidae: Western Pondhawk (Erythemis collocata)
Libellulidae: Flame Skimmer (Libellula saturata)
Libellulidae, Blue Dasher (Pachydiplax longipennis)
Immature and adult female Blue Dashers have black and yellow bodies and red upper eyes. The adult males have blue bodies and turquoise-colored eyes. As adult females grow older, their eyes also turn turquoise; in one image, an older female rests on a prickly pear fruit.
Libellulidae: Desert Whitetail (Plathemis subornata)
Libellulidae: Variegated Meadowhawk (Sympetrum corruptum)
Calopterygidae: Rubyspot (Hetaerina)
The common name refers to the red at the bases of the male's wings.
Coenagrionidae: Sooty Dancer (Argia lugens)
Coenagrionidae: Powdered Dancer (Argia moesta)
Coenagrionidae: Aztec Dancer (Argia nahuana)
Note how the blue bands on the Aztec Dancer's abdomen go all the way around, while the Arroyo Bluet's abdomen (below) is topped with black.
Coenagrionidae: Blue-Ringed Dancer (Argia sedula)
Coenagrionidae: Arroyo Bluet (Enallagma praevarum)
