Comprehensive Description

Agapostemon angelicus Cockerell

This is a widespread species in western North America, but, according to Roberts (1972), it is common only in the arid regions of the southwestern United States and northern Mexico. The female is polylectic like other members of the genus, but we have records of small numbers of both sexes from Larrea flowers in southeastern Arizona. Females are active in spring, summer, and fall and fly early and late in the day. They have been reported gathering pollen before sunrise from Cucurbita foetidissima (Linsley, 1960a) and before and after sunset from Mentzelia pumila (Loasaceae) in New Mexico (Linsley and Hurd, 1959) and Camissonia and Oenothera (Onagraceae) on the Colorado and Mojave deserts (Linsley, MacSwain, and Raven, 1963a, 1964; Linsley, MacSwain, Raven, and Thorp, 1973). Various aspects of the biology are discussed by Roberts (1969).

Males sleep gregariously in a horizontal position on dry flower heads of Heterotheca and other plants, tending to return to the same individual plant night after night (Linsley, 1962a).

Agapostemon angelicus

provided by wikipedia EN

Agapostemon angelicus, the Angeles striped sweat bee, is a species of sweat bee in the family Halictidae native to North America.[1][2] Unlike apid bees, members of the Halictidae family are not honey-producers, although they still are pollinators.

Subspecies

These two subspecies belong to the species Agapostemon angelicus:

  • Agapostemon angelicus angelicus
  • Agapostemon angelicus idahoensis

Description and identification

Angeles striped sweat bees are small, approximately 10 mm to 14 mm in length. The species exhibits distinct sexual dimorphism with the female being a metallic green bee across its entire body whereas males have a bright yellow and black banded metasoma. A. angelicus is easily confused with A. texanus. [3] Only the females have a small stinger.[4]

Distribution and habitat

The distribution of the Angeles striped sweat bee is limited to North America, from Canada south to Mexico. They are most commonly found in the western and central US, in and around the desert regions of the southwestern US.[4]

Behavior

As sweat bees, they get their name due to their attraction to human sweat. They often land on humans and lick sweat from the skin for the salt content. Males seem less likely to exhibit this behavior. They are polylectic pollinators, willing to feed off the nectar from any available pollen source.[5] While generally docile, females are capable of stinging.[4] Primarily active during the day, this species may take refuge on larger flowers during the night. The social nature of varies with females seeming to prefer to be solitary, while groups of males may gather on a single plant.[6]

Like most members of the Halictidae family, femalss Angeles striped sweat bees build their nests in the form of tunnels in soil, or other substrates. Halictidae bees do not feed their young honey, but instead leave balls of pollen in the nest where eggs are laid for the young to consume.[6] It's unclear if the nests of A. Angelicus are communally shared by females or not.[3]
