220 PESTS OF GARDEN AND FIELD CROPS 
Fic. 273.— The Clover Flower-midge. 
Florets showing arrested development. 
Original. 
feasible to cut for hay early, 
before the larv# have done much 
damage or completed their 
growth. The second crop will 
then be free of attack. 
Where timothy is combined 
with clover, the insect is con- 
trolled by clipping back the 
growth in May, thus retarding 
the blooming of clover past the 
danger point, since the heads 
will not be at the blooming 
period when the midges are 
flying. Here again the second blooming will be exempt. 
The Clover Seed Chalcid Fly (Bruchophagus funebris How.) 
The larva or grub of this tiny insect lives in the ripening seeds of 
clover or alfalfa. Its presence is seldom suspected, and the only evi- 
dence may be the shortage of the seed and the large quantity of empty 
hulls blown out with the chaff.
