As the month of April fades into May a certain beetle can be found flying noisily about its business. Cockchafers, often called Maybugs, are relatively large members of the Scarab beetle family. There are three different species of Cockchafer found in Europe;
- The common cockchafer, Melolontha melolontha
- The forest cockchafer, Melolontha hippocastani
- The large cockchafer, Melolontha pectoralis
Cockchafers spend most of their lives, 3 to 4 years, as larva, living underground, munching away at the roots of plants. In large numbers they can become pests, doing significant damage to crops.
It is as adults that they emerge above ground, flying around for roughly 5 to 6 week looking for a mate and feeding on the leaves of trees. They can usually be spotted making their noisy flight at dusk on warm evenings. You may even find them flying into and around your outside lights.

They are around 3cm long, with reddish brown wing cases and distinctive fan shaped antennae. Despite their intimidating size and noisy flight, they are actually harmless to humans. I once had one fly in the house and land on my big toe, waking me up from a nap!
Pesticides used farming in the mid-1900s brought them to the brink of extinction in the UK. However, changes in farming practises and pesticide use has allowed them to make a comeback. They can now be found across England, are particularly common in the south of England and the Midlands. They are much rarer in Scotland.
