Colletes floralis (Northern Colletes)
The norther n colletes (Colletes floralis) can be found along the west coast of the Outer Hebrides from Vatersay to Berneray. Although solitary bees, they nest colonially in sunny sandy banks.
Scottish Biodiversity List species of principal conservation importance.
Colletes bees are medium-sized, rather slender bees. The abdomen is black with a narrow white band on each segment. The upper side of the thorax and the face are clothed in orangey-coloured hairs. Males and females are similar in appearance.
Care is required to distinguish C. floralis from C. succinctus which is also present in the Outer Hebrides.
