The order Blattodea, is the order that consists of cockroaches. The cockroach that I have caught: the Australian Cockroach is in this order. Australian cockroaches are characterised by their long spiny legs and their two segmented antennae which are longer than their body. They are usually a dark reddish-brown in colour however can also be a pale brown or even a black. Adult cockroaches do have wings, but are not very good flyers. Their wings are membranous with toughened forewings which overlap left over right. They have three pairs of strong jointed legs as any other insect would. The head is small and points downwards; this protects their heads when they travel through the gaps and tunnels. They have hairy legs and eye-pattern on their thorax.
Despite their name, they are not native to Australia. They originated from Asia. They became totally adapted to domestic life.
Banksia robur is a small to medium shrub, 2 to 3m high and wide. The large leaves are stiff, leathery, egg-shaped and are coloured a dark shade of green.
Heads of blue-green flower buds arise from the junctions of branches and form into dense greenish-yellow flower but changing to brown with age. The robur species can flower from seed in 3 years and flowers are most commonly seen in winter or early spring. Seeds are held in hairy, woody follicles which are preserved on the plant for a considerable period. Reproduction occurs from this seed and can germinate within three to five weeks.
