Amblyteles. Many species of this genus overwinter in the adult 
stage in cracks in bark, in old borer cells in logs and 
beneath stones. During the winter months they may be 
found packed closely together in cells in logs, six to a dozen 
specimens, sometimes one species, often a number of 
species together. Many of the records show that they 
are primary parasites of Lepidoptera, and usually emerge 
after the host has entered the pupal stage.
