206 Notes on the Life-Histor}f of Ephestia kuhniella 



wandering the larva has found its place and spins its cocoon inside 

 which it lies with its ventral surface uppermost. Perhaps the favourite 

 spot for E. kuhniella is the ears of sacks, where the cocoons can be found 

 crowded together in great numbers, looking almost like one large 

 cocoon; but any suitable crevice will do. If it is autumn, the larva 

 may remain as it is inside the cocoon until next spring, or it may 

 pupate and hatch out almost at once, taking about a fortnight to do so. 

 In the latter case, the insect pairs and lays its eggs at once. These 

 generally hatch, and the winter is passed in the larval form
