Life-History. 
This moth is to be found on the wing in about the second 
week of July or, perhaps, a little before. Caterpillars were 
found seriously defoliating the Kharshu oak at the end of 
June, and some were pupating on the goth of the month. The 
larve roll up the young new leaves and feed inside the rolled up 
portion, Pupation takes place in the rolled-up leaves, or the 
jarva may take advantage of a depression in a leaf and pulla 
corner of the leaf over this, fixing it down by means of silk, A 
loose white silk covering is spun within this shelter, and the 
caterpillar then changes to a pupa within it.
