Halictus rubicundus
This record describes Halictus rubicundus (species). Recorded family: Halictidae. Recorded order: Hymenoptera.
Identification and Appearance

This small bee is a member of the family Halictidae known as sweat bees. It is small (about 1 cm) dark brown, with fine yellowy white bands across the apices of the abdominal segments, and a yellow fuzz of hairs on the tip of the abdomen. The legs are often somewhat orangey. Most solitary bees and wasps are difficult to identify, and can rarely be identified from photos taken in the field. All red-rated records should include a photo, or set of photos, showing the key characters, which may require the specimen. Please include a face shot, side, top and wings. Note whether male or female, explain how the specimen met the key characters and the key used. We will accept records identified by a recognised local or national expert, or that have been identified via the BWARS’ Facebook noting the name of the person/organisation identifying the record (e.g. ‘Stuart Roberts, BWARS Facebook’). H. rubicundus nests are constructed in the ground. Nests are dug in spring by a single female who typically rears a brood of 5-7 offspring. Fairly common and widespread in Britain.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Halictus rubicundus. Species-specific details appear above.
Group overview
Hymenoptera includes over 150,000 described species of ants, bees, wasps, and sawflies. Earth harbors approximately 20 quadrillion (20×10^15) ants, with a combined biomass of ~12 megatons of dry carbon - exceeding the combined biomass of all wild birds and mammals (PNAS, 2022).
Ecological role of the group
About 35% of the world's food crops depend on animal pollinators. The chocolate industry, valued at over $100 billion, depends on pollinating flies and midges. Ants are the dominant soil engineers in most terrestrial ecosystems, turning more soil than earthworms in many habitats.
Economic and practical significance of the group
Pollinators contribute $235-577 billion worth of annual global food production (FAO). In the U.S., bee pollination alone benefits crops valued at $18 billion annually, and honey bees are responsible for $5.4 billion in agricultural productivity. Between April 2023-2024, 55.1% of managed honey bee colonies were lost. The U.S. bee population dropped from 5 million to 2.5 million.
