Cratilla metallica

Dark-tipped forest-skimmer

Males guard a single small forest pool or mud hole for hours at a time, while the much scarcer females tend to stay higher up in the canopy.

The dark-tipped forest-skimmer is a moderately large dragonfly. Males have a metallic green thorax, a dark blue abdomen with pale blue bands near its base, and wingtips smudged with black that give the species its common name; females share the metallic sheen but lack the blue abdominal bands.

It breeds in small pools and ditches along shaded forest trails, where males defend a chosen mud hole for long periods against rivals. Females are seen far less often than males and tend to perch higher up among the trees rather than at the water's edge.
