Subfamily Chrysomelinae, FAMILY CHRYSOMELIDAE
- This page contains pictures and information about Leaf beetles of
Genus Calomela that we found in the Brisbane area, Queensland,
- Calomela species are particularly associated with Acacia.
Both adults and larvae feed on the leaf, some adults feed on the flower as
well. Calomela adults are in medium size, usually have the narrow and flat body shape.
Most of them are brightly coloured. They are native to New Guinea and
Australia. Larvae are in globular shape.
- Green Strip Leaf Beetle
- Calomela pallida, body length 10mm
- We found this green leaf beetle in Alexandra Hill and Karawatha
Forest during mid summer. It was
wandering on a young Acacia tree. Although it was brightly green in
colour, when it hided on a Acacia leaf in the shade, it was hardly be noticed.
It was a slow moving insects. After we took a few pictures, it slowly walked to
the leaf edge and flied to another young Acacia tree a couple of meters away.

are orange in colour with a dark brown "I"-Mark pattern on thorax.
There are also the dark drown patterns on wings cover. When we
go for bush-walking near Alexandra Hill in mid summer. On every young Acacia
tree (Black Wattle), we can easily found some of them resting
on the leaves. They are slow moving, seem doing nothing until we disturbed.
