Food-plant: Buds and catkins of burr-oak. 



This species was the latest of the oak-feeders to emerge; after 

 reaching its full size the larvae seem to find difficulty in pupating, 

 a number of ours dying at this stage. The larva is considerably 

 larger and more variegated than that of either ophelia or beuten- 

 muelleri. 



Catocala pura Hist. 



Ovum. Hemispherical, deep purplish-red banded with yellowish near base, 

 ribbed, the ribs branching into two or three shortly after leaving micropylar area
