Sand Tailed Digger Wasp
Cerceris arenaria
This record describes Cerceris arenaria (species). Recorded family: Crabronidae. Recorded order: Hymenoptera.
Identification and Appearance

A large species similar in size and markings to the Bee Wolf (Philanthus triangulum). 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 of the specimen, illustrating the key characters taken from a standard key, which should also be referenced (e.g. ‘Falk, 2015’). The full set of key characters are generally not visible in field photos and photos are rarely sharp enough. To aid in the verification of your records, please include face shot, side, top and wings. The notes should state whether male or female, and explain how the specimen met the key characters. Although NS may not be able to identify the species even if these reference photos are provided, the photos will be stored with the record and may allow it be identified in future. Alternatively, NS will accept records identified by a recognised local or national expert, or that have been identified via BWARS Facebook Group . If you have obtained this advice, please note the name of the person/organisation identifying the record in the ‘determiner’ field (e.g. ‘Stuart Roberts, BWARS Facebook’) rather than just a comment of ‘BWARS Facebook’. This wasp is associated with sandy soils and frequents inland heaths and commons. It can also be found on the coast especially around dunes and landslips. Active from the end of June or early July until mid to late August. The prey species are various weevils. Nests are deep burrows dug in the soil, from which side-tunnels radiate leading to cells at depths of 20 to 25 cm. In sandy areas, dense aggregations containing thousands of nests may form. Each cell is provisioned with 3 to 14 weevils, the number depending on prey size and sex of offspring. A locally common and very widely distributed species throughout much of southern Britain. No additional images available for this species.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Cerceris arenaria. 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.
