Please don't touch

This pair of mating Black blister Beetles (Meloe barbarus) that I came upon during my morning walk know they have little to fear from predators.

Touch one of these beetles and they will likely exude an oily substance from their joints known as cantharidin

that can cause severe blisters on skin and severe illness in grazing animals (such as horses) that eat vegetation that contains the Beetles.
So I just took my photos and left these two to continue on with procreation.
