It was not feeding on nectar

It was not feeding on nectar of this plant, as none of the Dactylorhiza have nectar (the spur is empty), and even if they had, the beetle would be unable to reach it by the 'official' route - it would need to bite into the spur as it has only short mouthparts.

These orchids not only parasitise fungi to get a lot of their nutrients, but they fool insects into providing pollination services for no reward. Masters of exploitation!

Thanks very much for that

Yet another example of just how clever nature is. Very good website too - interesting to see what you have up in the Highlands.
