Perdita rhois

Cockerell, 1901

Rhus Fairy Bee

Perdita rhois is a of mining in the , described by Cockerell in 1901. It is commonly known as the Rhus Fairy Bee, a name referencing its association with Rhus (sumac) plants. The species occurs in Central America and North America, where it functions as a . As a member of the Perdita, it belongs to one of the most diverse bee genera in North America, characterized by small size and often specialized - relationships.

Identification

Perdita rhois can be distinguished from other Perdita by its specific association with Rhus (sumac) plants. Members of the Perdita are generally small mining , typically 2–10 mm in length, with slender bodies and relatively simple body sculpturing compared to other . Species-level identification within Perdita requires examination of microscopic characters including , facial markings, and punctation patterns. The specific epithet 'rhois' directly references its sumac host association, which may aid in field recognition when found foraging on Rhus species.

Habitat

include areas where plants of the Rhus (sumac) occur, including open woodlands, forest edges, prairies, and disturbed sites. As a ground-nesting mining , it requires well-drained soils suitable for burrow excavation.

Distribution

Recorded from Central America and North America. GBIF distribution records indicate presence in Middle America and North America.

Diet

feed on nectar and pollen. Based on the and specific epithet, pollen collection appears specialized on or strongly associated with Rhus (sumac) , though the degree of oligolecy requires confirmation.

Host Associations

Rhus - pollen/nectar sourceInferred from epithet 'rhois' and 'Rhus Fairy '

Life Cycle

As a member of , it has a solitary lifestyle with females constructing individual burrows in soil. Females provision nest with pollen and nectar for larval development. Development likely includes , larval, pupal, and stages with potential for in response to environmental conditions, as documented in related Perdita .

Behavior

Solitary ground-nesting typical of . Females excavate burrows in soil and provision with pollen and nectar. Males likely plants or nesting to locate females.

Ecological Role

of Rhus (sumac) and potentially other flowering plants in its range. Contributes to diversity and function in North and Central .

Human Relevance

Contributes to services in natural and potentially agricultural landscapes. As a , it may serve as an indicator of quality and native health. No documented direct economic use.

Etymology

The specific epithet 'rhois' derives from the Greek name for sumac (Rhus), directly referencing the 's association. This follows a common pattern in Perdita where epithets often indicate host plant relationships.

Taxonomic History

Described by Theodore Dru Alison Cockerell in 1901, a prolific describer of North who named hundreds of Perdita based largely on associations and subtle morphological differences.
