Pest of the month: The Punctate Flower Chafer

For the past three years the soil of my bonsai trees have been getting infested with curl grubs. The worst case was a round pot with inner dimensions 4 X 20 cm, which had 24 of these bad boys (photo on the left). I reared some of them to find out what they are. They turned out to be the Punctate Flower Chafer Neorrhina punctatum, family Scarabaeidae (photo on the right). I was fighting them by repotting my plants, because even submerging the whole pot in insecticide solution doesn’t always kill them.
