     Abstract: The eggs of eight species of Plecoptera from Alberta were reared at constant temperatures between 2 and 25°C. All species' eggs hatched at 2°C but none hatched at 25°C. The relationships between temperature and number of days required for development and hatching were fitted to power equations. Slope values (b) ranged from -1.31 for Skwala parallela to 0.03 for Amphinemura banksi; the remainder fell between -0.94 and -0.68. All of these values, except for that for S. parallela, imply that stonefly eggs develop most efficiently at the lowest temperature within the favorable range or develop with equal efficiency throughout the favorable range.
