Terrestrial ectotherms are active between precise thermal tolerance values, from lower to upper limits that impacts their survival. Arround the temperature range where the xerophilous antlion larvae are active, there is a temperature close to the upper thermal limit where vital functions are optimal. No research at our knowledge is done on the thermal tolerance of Myrmeleon obscurus (Rambur, 1842), the present investigation identifies the thermal optimum of each larval stage in a range of four temperatures: 22, 27, 35 and 40°C. It comes clear that 35°C is the temperature at which no mortality is observed resulting to 100% of adults all viable; at this temperature M. obscurus has the shortest life cycle 45.43 days.
