Lithosticta macra

Lithosticta macra is a damselfly in the family Isosticticidae, a group known for their slender, delicate bodies and weak, fluttering flight compared to other odonates. Like other damselflies, adults are predatory, taking small flying insects on the wing, while aquatic larvae feed on invertebrates in seepages and slow-flowing water. Both life stages contribute to local food webs, serving as prey for birds, fish, and other invertebrates, and as indicators of water quality given their sensitivity to habitat disturbance.

The species is restricted to Australia, where it is associated with rocky habitats, typically seepages, streams, and pools within rugged rock formations that maintain consistent moisture and clean water. This specialization makes it highly dependent on the stability of these microhabitats.

Its vulnerable status stems from ongoing threats linked to mining and quarrying activity, which can degrade or destroy rocky seepage habitats through excavation, sedimentation, and altered water flow. Recreational activities, such as foot traffic, off-road vehicle use, or disturbance around rock formations, add further pressure by damaging fragile larval habitat and streamside vegetation. Because the species occupies a narrow habitat type in specific locations, even localized disturbance can have disproportionate effects on populations.

Specific population figures and trend data are not available, and the population trend is currently listed as unknown, limiting precise assessment of decline. Conservation attention has focused on habitat protection measures within its known range, though details of targeted management programs remain limited in published records.

The outlook for Lithosticta macra depends heavily on the extent to which mining operations and recreational pressures are regulated within its restricted rocky habitat range. Without clearer population monitoring, its long-term trajectory remains uncertain.
