Do not be alarmed by their size of up to 23mm, they are not aggressive and will simply go about their business of collecting nectar from flowers, chooseing to fly away from people. The male does not have the ability to sting. The males will chase other males in competition as well as females that they wish to mate. At this time they can be noisy, crashing into walls, windows etc. If caught and handled the female may sting as a means of self defence.

The name carpenter bee is due to their using dead wood to breed in. The female uses her mandibles to chew into the wood, creating tunnels into which she will lay up to 15 eggs. The small bits of wood that break away, will either be discarded or used to separate the egg cells. They are just as content to place their eggs in an existing tunnel such as a bamboo tube. Each egg will be provided with pollen on which to eat when it hatches.

These bees are very efficient pollinators of open flowers but can also use their size and weight to break into long tubular flowers from above and steal the nectar without collecting and distributing any pollen.

    1. Yes, they are out and about here in Grazalema now as well even though we are at 800 metres ot so… Its been a warmer winter and spring is well on the way already… 🙂 Feel free to join the Iberia Nature Forum and share any observations!

      1. Can they “bee” attracted to my area if I build bee hotels…? I am in the Alicante region in the mountain area at 640m…?

        1. Hi Rene!

          They can indeed! These carpenter bees like hollow stems of bamboo, for example, so a bee hotel made from sticks, bricks with holes and bamboo will be great for all the bugs and beasties!

          let me know how you get on!
