Cockroach IdentificationThee Australian cockroach is a common species of tropical cockroach, with a length of 23–35 mm. It is brown overall, with the tegmina having a conspicuous lateral pale stripe or margin, and the pronotum with a sharply contrasting pale or yellow margin. It is very similar in appearance to the American cockroach and may be easily mistaken for it. It is, however, slightly smaller than the American cockroach, and has a yellow margin on the thorax and yellow streaks at its sides near the wing base..
DescriptionThe Australian cockroach enter buildings at night from gardens/debris. It is generally prevalent in areas where winters are relatively mild. Despite its name, it isn’t a native species. Females deposit the ootheca (egg case) containing 24 eggs a day after production. After hatching nymphs take 6-12 months to develop into adults.
