- This page contains pictures and information about Gum Tree Shield Bugs in genera Poecilometis that
we found in the Brisbane area, Queensland, Australia.
- Shield Bug Feeding on gum tree trunk
- Poecilometis is the largest stink bug genera (50 species) in Australia. They are usually found feeding on
gum or other native trees. We found a number of different species in Brisbane. The adults
are 15-25mm in body length. Most are dark brown to reddish brown in colour.
They are usually found on Eucalyptus
or other native trees.
Poecilometis stink bugs can be distinguished from other similar
genera by wings longer than abdomen, with wing veins linear and
mostly subparallel. Antennae are basically 4-segmented but appearing 5-segmented in a number of species owing to a secondary subdivision of the 2nd antenna1 segment.
They have the typical shield-shaped body which is in general longer than
other stink bugs. The head is moderate elongate with round apex. The
juga do not surpassing apex of anteclypeus. Pronotum is strongly hexagonal
with lateral angles obtuse, acute or has the short slender spine. The triangular
scutellum usually constricted towards the apex. Veins on the membrane run
parallel with each others. Upper side of the whole body is covered with
coarse punctations. Legs are long and slender.
- Zebra Gum Tree Shield Bug
- Poecilometis histricus, body length adults 20mm
- We found those bugs easily at Macgregor and Wishart bushland in Brisbane, from late
winter to late summer. This is a medium size stink bug. On the body there are
the coarse dense brownish punctuations patches and lines of chocolate brown on
yellowish brown ground colour. More information and pictures please find in this page.
- Banksia Shield Bug
Poecilometis eximius, body length 20mm
- We found this brown shield bug once during early summer in Alexandra Hill.
It was resting on Banksia leaf. When disturbed, it flew to another Banksia tree
near by. This bug looks similar to the above species except it does not
have the black dot on wings. Click here for
