Bright red in the landscape always draws my eye (witness Wednesday’s beetles), so this burst of vibrant colour on a low-growing rose bush immediately attracted me. And the fact that the rose was ‘persuaded’ to create this object by the larvae of a tiny wasp is really quite mind-blowing. That wasp is a Bedeguar gall wasp (Diplolepis rosae), and you may remember my somewhat haphazard but ultimately successful attempts to see one of these wasps when I kept a gall in a jar to see what emerged (Bedeguar gall wasp, May 2020). This time I’m restricting myself to admiring the wasp’s astonishing creation.
