Euryglossina intermedia

Euryglossina intermedia is a small bee belonging to the family Colletidae, a group known as plasterer or masked bees for their habit of lining nest cells with a cellophane-like secretion. Like other members of its genus, it is minute in size and likely forages on a limited range of native flowering plants, playing a role in pollination within its native plant communities. Little detailed behavioural data is publicly available for this species, consistent with the limited research attention given to many small-bodied native bees in Australia.

The species is endemic to Australia, where it occupies temperate forest, general forest, and shrubland habitats. Its distribution appears to be geographically restricted, making it reliant on the persistence of specific native vegetation types.

The species is classified as Vulnerable, with a decreasing population trend. Threats include habitat loss and fragmentation from housing and urban expansion, road and rail infrastructure development, and clearing for annual and perennial non-timber crops. Logging and wood harvesting degrade forest habitat structure, while altered fire regimes and fire suppression practices disrupt the native vegetation this bee depends on for nesting and forage.

Invasive species, including introduced plants and possibly competing or predatory organisms, add further pressure, compounded by broader habitat shifting linked to environmental change.

Targeted conservation measures specific to this species are limited, though it may benefit indirectly from broader habitat protection within Australian conservation reserves and native vegetation retention policies. Research into the distribution, ecology, and taxonomy of small native bees like this one remains an ongoing priority for improving conservation planning.

Given continuing habitat pressures and the absence of species-specific intervention programs, the outlook remains uncertain, with population decline expected to continue unless habitat protection measures are strengthened.
