THE EFFECT OF TEMPERATURE ON THE LEG POSTURE AND SPEED OF CREEPING IN THE ANT LASIUS

Abstract
1. In the progression of L. umbratus the leg-spread and the frequency of leg movements increase as the temperature rises. 2. The speed of progression as influenced by temperature in L. niger shows a critical temperature at 20° C., and yields two values for µ: 10,700 between 16-20° C., and 22,900 between 20-25° C.
