Eucalyptus Leaf Beetle - ? Paropsisterna cloelia (? Chrysophtharta cloelia)


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

Body length 8mm
This Leaf Beetle are easily found on young Eucalyptus trees in Brisbane forest from late spring to summer. They are golden brown in colour. They can be found resting on leaves or stems.

When approached, they will drop onto the ground.

Host Plants

Notice in the picture almost every leaves have the Leaf Beetles' bite marks. Both adults and larvae feed on Eucalyptus leaves, however, larvae consume much most than the adults. Larvae feed mostly on the new shots and eat all the entire young leave. Adults mainly target on the edges of older leaves and leave bite marks  

Eggs and Larvae

DSCN7241.jpg (204134 bytes) wpe1D.jpg (29961 bytes) wpe1F.jpg (28304 bytes)
Eggs, 1mmx3mm                                                   1st instars, 3mm                                                    2nd instars and last instars
Females lay eggs on young leaves. Newly hatched larvae are black in colour. They start feeding in group on young leaf. They feed from leaf tip to base.

Larvae length 8mm                                                Larvae length 12mm                                              Larvae length 8-12mm   
The later instars are creamy colour with black head. They may feed individually or in group. In the second picture above all larvae was rearing the head and abdomen. It is their defense behavior. By doing this, the larvae release the eucalypt oil with hydrogen cyanide from their glands. Those chemical can kill other insects, such as ants.

Fully developed larvae move down the tree to pupate in the soil. 


In a early summer day, we found a group of small white larvae on a Eucalyptus leaf. We looked around and found that almost on all the leaves of the young Eucalyptus tree have some larvae feeding. We know those larvae are Chrysophtharta sp., and we wanted to know how their adults look like. We took some leaves and some larvae home and put them in a jar. Few days later, the larvae turned into pupae.

Pupa length 6mm 
One weeks later some pupae turned into adults. In the field, we do not normally see those pupae because they drop onto the ground and hide in the plants litter before pupation.

The Leaf Beetle Nature Enemies

We found the following nature enemies of this Leaf Beetle species. We believe those nature enemies are common for most of the Leaf Beetles. 
Parasite Wasp
DSCN7255.jpg (221286 bytes) wpe10.jpg (44769 bytes) wpe12.jpg (29361 bytes)
Wasp body length 3mm
We found that the Leaf Beetle eggs were heavily parasitised by the tiny parasitic wasps, especially from mid to late summer season. The batches of Leaf Beetle eggs that we collected in late summer season are all parasitised. There are more information on Leaf Beetle eggs parasitoids  in this section.
Glossy Shield Bug
wpe19.jpg (17079 bytes) wpe1B.jpg (26313 bytes)
On the gum tree that we found those Leaf Beetle adults and larvae, we also found a few Glossy Shield Bug nymphs wandering on stems looking for their prey. The Predatory Shield Bug prey on all kinds of soft body insects including caterpillars and Leaf Beetle Larvae. 
Spined Predatory Shield Bug
wpe1.jpg (53181 bytes) wpe6.jpg (38041 bytes)
The Spined Predatory Shield Bug is also a common predator of the Leaf Beetle larvae. In mid-summer, we saw a young gum tree in Karawatha Forest which was heavily infected by the Leaf Beetle Larvae. However, near every group of feeding beetle larvae, there was a Spined Predatory Shield Bug attacking them.
