DescriptionNewly hatched gypsy moth larvae are morphologically and behaviorally adapted for airborne dispersal. The diel periodicity of both hatching and dispersal from the egg mass and photopositive behavior assure that larvae are in optimal position for dispersal when air turbulence is maximal at midday. The rate of larval activity depends upon ambient temperature and relative humidity (R2 = 0.77). The larvae continually trailed silk and did not feed upon reaching the foliage. Rather the larvae appeared predisposed to disperse and were readily dislodged by slight winds.
