Insects Injurious to the Apple. 17 



TREATMENT. 



All that is necessary as far as present attacks have gone is hand- 

 picking the caterpillars. Should they ever occur in such large 

 numbers as I have seen them in osier beds in Middlesex and 

 Huntingdonshire, then spraying with arsenate of lead would prove 

 successful.

THE APPLE CLEARWING. 



(sEgeria myopiformis. Bork.) 



On the 21st of June, 1907, larvae and pupae of this Clearwing 

 Moth were sent me from the Croydon district by the Secretary of 

 the Horticultural Mutual Improvement Society (3). 



The larvae were taken out of an apple tree, Warner's King, 

 where they had been working havoc underneath the bark. They 

 occurred in patches. In many instances they were found in the 

 wounds caused by Woolly Aphis. 



" The attacked trees are about six years old," wrote the Secretary. 

 Mr. Boshier, " and are in good bearing condition." 



On the 26th of June a further lot of pupae were sent, taken from 

 Duchess Favourite, Warner's King, Colonel Vaughan and Winter 

 Queening. The larvae were mostly found 

 about 7 feet from the soil. 



This Clearwing Moth (Fig. 2) is some- 

 what similar to the Currant Clearwing in 

 general appearance, but can at once be told 

 by the broad red belt on the abdomen. 

 The length is about 20 mm., with a wing

expanse of 22 to 25 mm. The head, thorax FIG 9 [F - E - 



and body are black ; the latter has a bright THE AppLE CLEA ~ WING MOTH . 



red band above, white beneath in the male; (^; ger ia myopiformis. Bork.) 

 in the female the underside is only edged 



with white ; the tail fan is black. The wings are transparent, with 



dark sealed areas. The rnoths fly by day, and are found in May, 

 June and July.
