Photo: JeanIt is a brown flower beetle, Glycyphana stolata (Coleoptera: Scarabaeidae). The species was introduced from Eastern Australia about 15-20 years ago, most likely in potting mix. Adults are increasingly common on flowering plants including fruit trees, introduced ornamental plants and also on native trees and shrubs. Larvae are very common in soils rich in organic material feeding on decomposing plant material, sometimes building up very high numbers (over 15-20 grubs in a 20 cm diameter pot). At this stage it is not a pest of economic significance. Andras Szito Ag Dept 2019
