Gum Tree Shield Bug

Morphology

This species is distinguished by its light colour and conspicuous pale streaks on the dorsal surface.

Evolution

This genus has 45 described species and this subfamily is the largest in number of species in all subfamilies of Heteroptera.

Behaviour

Poecilometis are typically found on the trunks of trees, and sometimes under bark. Even when not seen, they can sometimes be detected by loud, intermittent buzzing as they fly from branch to branch. When approached they will often walk to the other side of the trunk or farther up the tree, generally moving in a jerking manner. 

Method of reproduction

Sexual

Habitat

Terrestrial

Species of this family are usually associated with species of Eucalyptus or Callitris, sometimes with other trees or shrubs. They are generally found under bark, on vegetation and in leaf litter.

Distribution

This species is found in northern Western Australia, Northern Territory, Queensland and South Australia. It has also been found in central New South Wales.

Life Cycle

As with other true bugs, pentatomids have incomplete metamorphosis: upon hatching from their egg they go through several nymphal stages, each progressively larger and more developed than the next. In the final stage they moult into the adult, which is distinguished from the nymphs by the presence of fully developed wings.
