Silver Wattle Leaf Beetle - Calomela ioptera


This page contains information and pictures about Silver Wattle Leaf Beetles that we found in the Brisbane area, Queensland, Australia.

Body length 10mm
Near the hill top of Anstead Forest Reserve, there were many Queensland Sliver Wattle trees (Acacia podalyriifolia). On each tree, we easily found one or two Silver Wattle Leaf Beetles. They were either feeding, resting or wandering around. We found one was laying eggs. Those Leaf Beetles did not make noticeable damages to the trees. It was March 2009.

Silver Wattle Leaf Beetle has the standard body shape of Calomela sp.. The head and thorax are orange brown in colour with black eyes and black antenna. The legs are orange brown too. The wing covers are orange brown covered with lines of metallic green-blue dots. The green-blue colours are slightly different between individuals.

This leaf beetle seem like to feed only the surface white waxy layer on the leaves, although we also found bite marks on other leaves.

Like most other leaf beetles, this Silver Wattle Leaf Beetles also apply the drop and play dead escape method. When disturbed, the beetle dropped onto ground and play dead. We put it on our hand, the beetle started walking around after half a minute.

On March, we found the beetle laying eggs on leaf. The eggs are creamy yellow, about 2mm long.

The Larvae

Body length 6mm                                                                                                                              
Different stages of Larvae and adults can be found on the same host plant. The Larvae are pale green in colour, well camouflaged among the host plants.
