Blue Dasher
Pachydiplax longipennisBlue dashers are aggressive, highly visible dragonflies commonly seen perching on emergent vegetation around still waters. Mature males feature chalky blue abdomens, striped thorax patterns, and bright metallic green eyes, while females display distinct yellow stripes along a brown abdomen. They make brief, rapid hunting sorties from a favorite stem, snatching mosquitoes and midges right out of the air before returning to the same spot.

Responsible observation
- Observing: Look for males resting on twigs near water, raising their abdomens on hot sunny days to regulate body temperature.
- Photography: Move slowly toward their perching stem, as individuals routinely fly back to the exact same location after flushing.
- Habitat timing: Visit sunny pond margins during warm summer mid-afternoons when flight activity reaches its peak.
