Ivy Mining Bee flying to cliff-face nest

Post by dunksargent »

Langdyke Countryside Trust UK 'Swaddywell Nature Reserve' Ivy Mining Bee (Colletes hederae) observation trip 21 September. Camera and tripod set up on limestone cliff slope habitat where the solitary bees nest in cliff crevices. They also excavate (mine) nest holes in the ground. Species was new to UK in 2001 and 2020 is the first year observed at Swaddywell ... a disused limestone quarry.

This specimen is flying to a nest in the cliff crevice at top RHS ... where there are several separate sub-crevices used as nest holes.

Photomacrography.net will not host videos, but if they are hosted someplace else it is certainly OK to link to them.
