Small populations of this pest were detected in January 2010 in Dove Meyer Robinson Park, Parnell and the Auckland Domain. It was subsequently found in wider locations in Auckland including Greenlane, Newmarket and Remuera. It is now considered established in New Zealand.
The adult is an orange coloured beetle, although the colour does vary. They have around 26 black spots on their back and are 7-10mm in size.
The hadda beetle should not be confused with the common lady bird found throughout the country.
Causes feeding damage to foliage – the leaf surface is scraped away from the main leaf vein leaving irregular holes or strips. Heavy feeding damage give leaves a distinctive lace-like appearance. Both adults and larvae feed on the host plants unlike most other members of the same group who are generally predators.
The beetle can fly up to 50 metres. It can also be spread by the movement of plant material or hitch hiking on other structures.
