Melolontha hippocastani Fabricius, 1801 - (horse chestnut cockchafer)
The beetle is found in many parts of Europe and eastwards up to Siberia and Manchuria. Damage is mainly done through the larvae - white grubs - which attack the roots of various plants, mainly forest trees like pines and firs. Fruit trees may be also attacked. For breeding, sandy soil is preferred which is often associated with outbreak areas. The adults feed on the young shoots of the trees. Outbreaks can weaken trees significantly.
In contrast to the common cockchafer, Melolontha melolontha, the development cycle is normally 4 years. However, 3 and 5 years have been also reported. Development in a population is well synchronized and masses of adults emerge during May and June of some years, but not during other years.

In the past, control has relied on treating the soil in outbreak areas with pesticides like organochlorides or organophosphates. More recently, control focused on the aerial application of pesticides during periods of adult swarming and environmentally friendly products like neem are under development. In addition, preparations of Beauveria brongniartii are now commercially available for application against the white grubs.
The adult is between 20-30 mm long. The main morphological difference to the common cockchafer is the shape and colour of the pygidium tip which is shorter, but widens slightly at the end. The difference is especially clear in males (see illustrations below).
