Identification
Males show green thoracic stripes and a blue abdominal tip; females may be bright orange when young and become green, blue-gray or dark.
Males show green thoracic stripes and blue at the abdominal tip. Females may begin bright orange and mature through green, blue-gray or dark forms, so the thoracic and terminal structure must carry more weight than color phase.
03 / Field guide
Documented range
Pacific Forktail ranges from British Columbia and Saskatchewan south to Baja California Sur, Sonora and New Mexico.
Arizona, California, Colorado, New Mexico, Nevada and Utah support the species; Texas is beyond the checklist's stated southern interior limit.
04 / Field guide
Habitat & flight period
Ponds, marshes and slow streams with abundant shoreline vegetation.
Adults can fly through much of the year in mild coastal California, while northern and mountain populations have a summer window.
05 / Field guide
Finding strategy
Inspect low sedges and rushes along quiet shorelines. Its abundance should not replace a check of face, thorax and terminal pattern.
Inspect low sedges and rushes around quiet shorelines and slow channels, including mild coastal sites where adults can fly well beyond the inland summer. Abundance is not a substitute for checking Black-fronted or Plains Forktail at overlapping sites.
06 / Field guide
Similar species
Black-fronted and Plains Forktails overlap inland; Eastern Forktail is possible in parts of the interior. Female forms are especially challenging.

Photography in the field
Photograph at eye level with the perch when possible; a distant shoreline becomes a clean, tonally soft background.
Protect the water edge, keep a working distance, and leave the insect and its perch as found.
