Bug in Spain
Just wondered if you could help identify this bug that appears quite extensively in the garden of our house in Andalucia, Spain. They are about 6 cm long and “seem” perfectly harmless, but it would just be interesting to know more about them. Any help appreciated. Many thanks
El Berrueco, Cadiz, Spain
This is a Blister Beetle, probably in the genus Megetra. Though you call them harmless, Blister Beetles exude a fluid that contains Cantharidin, and if handled, it can cause blistering of the skin.

We have just identified this species as the Red Striped Oil Beetle, Berberomeloe majalis, based on information on the Wildside Holidays website.
