The Geoscapheus robustus (a close relative of the giant burrowing cockroach) is native to Australia and mostly found in the semi-arid and drier regions of the continent. They are slightly smaller than their giant cousins, measuring up to 4cm in length, and can live for several years. Inside their natural burrows, the temperature remains about 20degrees Centigrade all year. Their preferred temperature range is 18 - 26 degrees, so keep them in a warm place in winter. If the temperature remains consistently below 10 degrees, a heating arrangement in the form of a 40 watt bulb is advised. If it gets really cold, a better heating system must be implemented like a thermostatically controlled heat pad.
The staple diet of Geoscapheus is dried, dead gum leaves, which they collect from the surface. So obtain dead leaves from the ground or from dead branches. They won't eat leaves which are green or yellow or damp, i.e. any leaves containing moisture are unsuitable. They prefer leaves which are crushed, rather than whole. They also prefer the less aromatic types, although this isn't critical. A handful of leaves at a time will be sufficient, and discard old uneaten leaves from time to time. They will also nibble the bark from gum twigs, and may sample a variety of fruits and vegetables, e.g. banana, apple, carrot, lettuce, potato etc., but remove any uneaten portions after a few days, or they will go mouldy.
