Nomada vicina

Cresson, 1863

Neighborly Nomad

Nomada vicina is a of in the , first described by Ezra Townsend Cresson in 1863. As a member of the Nomada, it exhibits kleptoparasitic , laying in the nests of species rather than constructing its own nests. The species is known from North America with confirmed records from Vermont and other regions. Like other Nomada species, it likely targets nests of mining bees in the genus Andrena. The "Neighborly Nomad" reflects both its parasitic lifestyle and its taxonomic proximity to related species.

Identification

Nomada vicina can be distinguished from other Nomada by examining morphological features typical of the , including reduced (pollen- hairs) on females due to its cleptoparasitic lifestyle. Males and females exhibit the characteristic -like appearance of , with relatively sparse body hair compared to non-parasitic . Precise identification to species level requires examination of genitalic structures and other detailed morphological characters, as many Nomada species are visually similar. The species lacks the dense branched hairs seen in pollen-collecting bees, instead possessing short, simple hairs.

Distribution

North America; specifically recorded from Vermont, United States. The ' range within North America requires further documentation beyond the confirmed Vermont locality.

Host Associations

Andrena - Likely based on genus-level Nomada biology, but specific host for N. vicina not documented

Ecological Role

As a kleptoparasitic , Nomada vicina functions as a nest of solitary bee , likely Andrena mining bees. This parasitic relationship represents a natural control mechanism within bee . The species contributes to and serves as an indicator of healthy bee populations, as its presence implies functional nesting for its hosts.

Taxonomic Status

The was validly described by Cresson in 1863 and remains accepted, though detailed modern taxonomic revision may be needed to clarify its precise boundaries and relationships within the large and taxonomically complex Nomada.

Data Deficiency

Despite being described over 160 years ago, Nomada vicina remains poorly documented in the literature, with limited information on its biology, associations, and full geographic range. This reflects a broader pattern of data deficiency for many North Nomada .
