68 Insect Pests. 



spring, and may be easily collected at dusk by shaking the blossoms 

 over an open umbrella. They occur on the wing in March and 

 April, and a few straggle 011 into May. 



The caterpillar is green, dotted with black, with a dorsal yellowish- 

 green line and two lateral lines of the same colour. They may be 

 found in May, June and just into July, and normally feed on the 

 leaves ; the habit of eating the fruit and occurring on apples appears 

 to be abnormal. When mature they reach ~\.\ inch in length, and 

 then pupate in the soil. They are said to form a loose cocoon 

 of particles of earth, but the one sent by Mr. Getting changed to 

 deep rich brown pupa nakedly in the breeding cage. 



The moths hatched out in February owing to their having been 

 kept in a warm laboratory.

Although little or nothing has been recorded concerning this 

 insect as an enemy of the apple it is nevertheless very harmful. 

 Carpenter (1) refers to it in Ireland, having noticed it on apple branches 

 sent from County Fermanagh. Mr. Jeffreys of Ashford many years 

 ago pointed out to me the importance of this insect to apple growers, 

 but no direct observations have been made on it, although it occurs 

 in small numbers all over the country. The damage is done by the 

 small caterpillars feeding in the buds and blossoms of the apple and 

 pear. They feed mainly upon the petals of the blossoms, but also 

 gnaw the strigs and even young leaves ; now and then one notices 

 some of the blossoms of the trusses spun together by this caterpillar,

 the culprits are carefully examined. It is also known as Eiqrithecia 

 rectangulata.
