Nomada leucophthalma

This record describes Nomada leucophthalma (species). Recorded family: Apidae. Recorded order: Hymenoptera.

Identification and Appearance

Nomada leucophthalma - Nomada leucophthalma

This is a large cuckoo bee (12 mm) with dark red, orange-tipped antennae (instead of just orange in the case of Nomada flava ) and dark legs. It has a yellow and black striped abdomen with a red band at the front. It also has a thick pile of orange hair on the mesonotum. It is similar to N. flava and others, but the dark antenna and legs plus the early flying season help to distinguish N. leucophthalma . 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’). It favours hedgerows and meadows, where it searches for the nest holes of Andrena clarkella in which to lay its eggs, and feeds on nectar from flowers such as Colt's-foot. The adult is on the wing early in the year - from March to May. It is a parasite of the small bee Andrena clarkella . Fairly frequent and widespread in southern Britain.

About Flies: the wider group

Order-level background for Hymenoptera, the group containing Nomada leucophthalma. 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.
