Nomada australis

Mitchell, 1962

Five-spined Nomad

Nomada australis is a of cuckoo bee in the Apidae, described by Mitchell in 1962. As a member of the Nomada, it is a kleptoparasite that lays its in the nests of species. The species is found in North America, with confirmed records from Vermont, United States. Like other nomad bees, it lacks the branched body hairs typical of pollen-collecting bees and relies on other bees to provision its offspring.

Identification

As a Nomada , N. australis can be distinguished from non-cuckoo bees by its relatively sparse, unbranched body hairs and -like appearance. Specific diagnostic features for N. australis include the five spines referenced in its , likely on the scutellum or other thoracic structures, though detailed morphological descriptions are not widely documented. Identification to species level within Nomada typically requires examination of genitalic characters and precise coloration patterns.

Distribution

North America; specifically recorded from Vermont, United States. The name 'australis' (southern) may reflect the type locality or relative distribution within its range rather than a southern continental distribution.

Host Associations

Andrena species - probable Based on -level association; Nomada typically parasitize nests of mining bees in the genus Andrena

Ecological Role

Kleptoparasite (cuckoo bee) that exploits nests of . As a nest , it contributes to of its host species and represents a component of native bee diversity.

Taxonomic note

The specific epithet 'australis' is somewhat misleading given the North American distribution; this likely reflects the original description context or relative position within a group rather than a southern geographic range.
