Cockroach or Cockchafer?
The cockchafer beetle is often misidentified as a cockroach but they are very different.
The cockchafer is also known as the may bug as May is the time of year it makes it an appearance. Cockchafers are not a public health pest and are harmless and do not require a treatment. Cockchafers can fly and will often fly into a property at night being attracted by a light, best advice is to collect it up and pop it back outside.
The cockchafer larvae (grubs) are not popular with gardeners or farmers as they can be destructive.
