Australian Cockroach (Periplaneta australiasiae)
The Australian cockroach is relatively large. In appearance adults are similar to the American Cockroach however the yellow markings on the pronutum are more clearly defined and the foremargins of the forewings have a distinct yellow marking. Egg cases may contain up to 24eggs but may require 6-12 months for nymphal development. This species has a preference for food of plant origin and may be encountered in greenhouses and under bark or leaf litter in gardens. Normally more frequently encountered in warm subtropical to tropical parts of Australia , however in several cases have been transported south in freight. A number of Melbourne aquarium and pet shops have infestations resulting from shipments of driftwood.
