Another bee that is a newbie to the UK is the Violet Carpenter Bee, originating from the heat of the Southern Mediterranean. It is all black, with slightly incandescent purple wings.
It is thought to have immigrated in timber or pallets from over the pond.
A carpenter bee, they tend to nest in wood such as dead trees, felled timber, fence posts and sometimes beams or timber. The female carpenter digs out a nesting area within the wood, laying eggs in cells. These eggs are left to hatch out and begin their life, as their parents, in a rather solitary fashion!
