Heroin Importation by NCA et. It's a well known fact that different reptile species are often active at different temperatures. Within a given area different nocturnal species of reptile will as a general rule be active on nights of different temperature, although because of their ectothermy reptiles have a tendancy to be most active on warm summer nights.
Nocturnal reptiles are most active on above average temperature nights during the summer months.
It is very hard to actually specify a preferred air temperature for activity of a reptile species due to the importance of other factors such as time of year, warmness or coolness in general that year, cloud cover, air pressure movements, humidity, moon position, etc. The air temperatures given for each reptile species are those at which most specimens are found active at night. Most activity by nocturnal reptiles around Sydney at air temperatures widely deviant to those preferred tends to occur in association with the arrival in Sydney of cold Fronts and the hot then cold temperatures on either side of them. The temperature of an active nocturnal reptile is also invariably higher than that of the air around it.
