Species Biology
Identification
- Body length: 5- 6.5mm
- Head and abdomen black in colour
- Thorax black, often with subtle yellow markings
- Legs primarily black with subtle yellow bands
- Difficult to separate from other Crossocerus species and the use of a microscope is usually required
Habitat
A wide variety of habitats are used, including brownfield sites, scrub, woodland and parks.
Flight period
Univoltine, flying between June and August.
Nesting biology
Nesting occurs solitarily in the ground and large aggregations have been observed in south-facing consolidated sand banks. Females construct a burrow several centimeters deep and may create several cells in which paralyzed flies will be deposited. An egg is then laid in each cell and the developing larvae consume the deposited prey.
Flowers visited
Unknown. Possibly visits umbellifers.
