Psila rosae Fabr. 
CARROT RUST FLY 
Ord. Diptera: Fam. Psilidae 
Celery roots infested with a dipterous larva, which subsequently 
proved to be this species, were received Dec. 30, 1901, from James 
Granger, Broadalbin, who states that the attack was confined to 
the roots and crown, never interfering with the stalk. Several 
larvae were taken from one root, and their burrows, about 4), 
inch in diameter, were fined with reddish particles of comminuted 
tissue. The galleries were found in the roots near the crown and 
also in the crown and frequently ran obliquely for a distance 
partly around the root or crown, as the case may be, and in some 
instances they were near the center of the infested plant. The 
attack was a serious one, as is evidenced by the ruining of about 
6000 plants. Traces of the insect were found aii over a field 
containing some 60,000 plants. 
Introduction and injuries in America. This is a European insect, 
which prior to 1885 was not known to occur in this country. It 
was then reared by Dr Fletcher from carrots purchased in the 
market at Ottawa, where the following year he found young 
carrot plants in a garden badly attacked. The same year 
a great deal of damage was done, particularly to stored roots
