166 PESTS OF GARDEN AND FIELD CROPS 
Fic. 183.—Cocoon of the Lesser Clover 
Leaf-weevil in clover head. 
Original. 
Large numbers of the grubs 
often die from a fungous dis- 
ease, and may be seen coiled 
around the stems near the top. 
Cattle eating clover on which 
many of these dead larve 
are present, are apt to be 
mildly poisoned. 
The Lesser Clover Leaf-weevil 
(Phytonomus nigrirostis Fab.) 
Small holes are eaten in the 
young and tender leaves of 
clover, and later, at the bloom- 
ing period, the inner parts of 
the heads are destroyed by a 
tiny grub, the immature stage of a small, greenish snout beetle.

The beetle spends the winter in rubbish or other shelter. Emergence 
begins with warm weather, and egg-laying continues for several weeks.
