Understanding the behaviors of Madagascar Hissing Cockroaches (Gromphadorhina portentosa) under varying temperatures will allow us to understand the biology of these roaches and how their metabolism and energy depends on temperature. The information collected in trials can open new possibilities of education about other Giant Cockroach species and invertebrates alike. Through five minute trials, Madagascar Hissing Cockroaches were observed both visually and through electronic collection of temperature and oxygen levels. The cockroaches were observed at temperatures of 14℃, room temperature, and temperatures of 30℃. Collected data showed that at higher temperatures, more oxygen was used but the roaches were more dormant and at lower temperatures, less oxygen was used and the cockroaches were also dormant.
