Caliagrion billinghursti

This damselfly belongs to the family Coenagrionidae, a group of slender, narrow-winged Odonata typically identifiable by their delicate bodies and comparatively weak, fluttering flight compared to larger dragonflies. Like other coenagrionids, Caliagrion billinghursti is likely predatory as both larva and adult, with aquatic nymphs feeding on small invertebrates and adults taking flying insects on the wing. As adults, damselflies of this type often rest with wings folded along the body and are frequently observed near still or slow-moving water, where they play a role in regulating insect populations and serve as prey for birds, fish, and other predators.

Caliagrion billinghursti has been recorded in Australia and American Samoa, though detailed habitat associations have not yet been formally assessed. As with many coenagrionids, it is presumed to depend on freshwater or wetland margins for breeding, since larvae require aquatic environments to develop.

The species is classified as Vulnerable, with ongoing threats linked to livestock farming and ranching, and to the expansion of annual and perennial non-timber crops. These agricultural pressures can degrade or eliminate the wetland and riparian habitats damselflies rely upon, through water extraction, pollution, sedimentation, and vegetation clearance associated with grazing and cultivation.

No specific population figures are available, and the population trend is currently listed as unknown. There is no documented information on targeted conservation programs for this species at present. Given the continued presence of agricultural pressures within its range and the lack of detailed habitat or population data, the outlook for Caliagrion billinghursti remains uncertain, underscoring a need for further survey work and habitat assessment to inform future conservation action.
