Size 7 to 9 mm. This is the smallest species of Colletes in the UK. It is more grey brown than other similar species, and has sparser thoracic hair (allowing the mesonotum to shine through).
May be seen visiting flowers and at its nesting sites.
Mid June to mid September. Females provision the nest entirely from flowers in the family Asteraceae, Tansy, Daisies and Ragwort being common forage plants.
Will nest in soft steep or vertical faces such as sandstone cliffs, steep cuttings etc. It will also nest in soft mortar joints in brickwork and can cause considerable problems when a large number f bees use the same site.
Widely distributed throughout England, Wales and the Channel Islands, but scarce in Scotland, where it is known only from scattered coastal sites as far north as Invernesshire.
Fairly frequent in Leicestershire and Rutland.
