Epeolus australus
Epeolus australus is a cleptoparasitic (cuckoo) in the Epeolus, a group of bees that do not construct their own nests or collect pollen. Like other members of its genus, this invades the nests of bees, primarily those in the genus Colletes (polyester bees), where it lays that hatch into that consume the host's provisions and offspring. The species is one of approximately 43 known Epeolus species in North America, with new species in this genus continuing to be described due to their small size, rarity relative to their hosts, and -like appearance that makes them difficult to detect.

More Details
Taxonomic context
The Epeolus underwent revision for Nearctic north of Mexico in 2018 by Thomas Onuferko, who described 15 new species including Epeolus attenboroughi. This revision brought the total known North Epeolus species to 43. Epeolus australus was not among the newly described species in this revision, indicating it was previously known to science.
Etymology
The specific epithet 'australus' is Latin for 'southern,' likely referring to some aspect of the ' geographic distribution relative to , though the precise naming rationale is not documented in the provided context.
Conservation implications
Like many rare cleptoparasitic , Epeolus are difficult to assess for status due to their naturally low relative to , specialized ecological requirements, and challenges. The rediscovery of related rare (such as Epeoloides pilosulus) in unexpected locations suggests that continued and documentation of historic records are essential for conservation assessment.
