The Common-Dotted Fruit Chafer is a shiny-black beetle with white spots. It belongs to the Scarab beetle family (Scarabaeidae), also referred to as dung beetles because the larvae develop within cattle manure. These beetles are active during the day and have a strong attraction for flowers and dung. The adults are nectar feeders, so are vital pollinators of some indigenous plants, such as lily, orchids, protea and asclepiad. These beetles sometimes use the anthers of lilies as a launchpad for take-off!

The adults may nibble on the petals of ornamental plants, however, feed mostly on the nectar.
Flower chafers are brilliant pollinators. Their larvae may also help the decomposition of animal dung.


A small beetle, barely reaching a centimeter. They're shiny black with numerous white spots. The sides of the body a reddish-brown. The stomachs possess grey hairs, perfect for carrying pollen from plant to plant! You're most likely to see them on flowers or in fruit bushes and trees.


These beetles may attack the petals of some ornamental plants.

Biological treatment

These beetles don't tend to be aggressive feeders. They may eat the petals of flowers, but ultimately, are probably important pollinators for several indigenous plants. If in the instance these beetles are numerous, handpicking them from flowers and dropping in soapy water is sufficient for their control.

Chemical treatment

It's not advised to use pesticides against this insect. Pesticides tend not to penetrate the hardened wingcases so are less effective as a means of treatment. Larvae develop within dung so there's no need for lawn treatment where these beetles are present.


These beetles are attracted to lilies, orchids, protea and asclepiad. Arum Lilies are one of their favourites.
