Larva—" Normal (S. exitiosa), and almost absolutely like S. albicornis. The area about the 

 mouth seems more uniformly dark ; otherwise the same description will apply." (Dyar, MS.) 



This species appears to be most common along the Pacific coast, where it is 

 a pest to the strawberry. The larva makes a large irregular channel in the crown 

 or main roots, usually killing the plant. The moths make their appearance late 

 in June and are on the wing until late in July. The larva also infests the roots 

 and lower parts of the canes of the common garden raspberries and blackberries.
