This species is Peltoschema basicollis. This orange beetle with black spots is clearly a coccinellidae mimic. These beetles are monophagous, obligate feeders on Acacia buxifolia and the beetles were restricted to a small stand of this acacia in a small section of the park. These are easily and commonly mistaken for ladybirds but feature a black suture. There are at least three species of Peltoschema in a complex of ladybird mimic species.
Differentiate from co-existing Noon-flower by triangular cross-section of leaves, paler leaves that are often red-tinged, and flowers that do not ascend above leaves (in Noon-flower flowers sit above leaves).
Large, hairy caterpillar found feeding on Cattle Bush (Alectryon oleifolius subsp. canescens). Size similar to adult pointer finger, both in length and girth.
Thanks to Cathy Powers and Peter Marriott for identification.
