Metallic Green Carpenter Bee

Xylocopa aerata is a large solitary bee recognisable by its robust body and metallic green to blue-green sheen, sometimes with coppery highlights. Females excavate nest tunnels in dead wood, including fallen branches, tree stumps, and structural timber, where they provision brood cells with pollen and nectar. As adults forage across a range of flowering native plants, they act as pollinators, and their buzz-pollination technique makes them particularly effective at fertilising certain flowers that other bee species cannot service as efficiently.

The species is restricted to Australia, occurring in temperate forest, forest edge, and shrubland habitats. Its distribution is closely tied to the availability of suitable dead wood for nesting, which limits it to areas retaining mature or decaying timber.

Population decline is driven by multiple overlapping pressures. Bushfires and altered fire regimes, including fire suppression practices that change vegetation structure, degrade both nesting substrate and forage plants. Broader habitat shifting and alteration, land conversion for annual and perennial non-timber crops, and ongoing logging and wood harvesting all reduce the amount of dead wood available for nesting and fragment remaining populations.

Conservation efforts for this species remain limited and are largely embedded within broader native forest and woodland management, habitat protection measures, and post-fire ecological recovery monitoring in affected regions. Targeted, species-specific conservation programs are not well established.

Current population figures are not well documented, but the population trend is assessed as decreasing. Given the ongoing combination of fire impacts, land-use change, and continued loss of nesting habitat through logging, the species' trajectory remains one of concern, with its Endangered status reflecting sustained pressure on the specialised habitat conditions it requires.
