Insects Injurious to the Apple.

and figures the female with two black spots on each segment, but 

 these do not show so clearly in any females I have noticed. The 

 moths appear from the end of October onwards until the beginning of 

 February. The females crawl up the tree trunks, just in the same 

 way as the Winter Moths. The ova are deposited on the buds and 

 twigs, in bark crevices and on pruned surfaces. The caterpillars 

 hatch out later than those of the Winter Moth, usually in April. 

 They are readily told from the Winter Moth by their colour ; the 

 back is chestnut-brown, and the sides a pale creamy-yellow to bright 

 yellow, the venter pale yellow to pale greenish-yellow, and the 

 spiracles pale with dark rims. Their means of progression is just 

 like that of the former species. When mature they reach 1^ inch 

 in length. They have been sent by various correspondents as late 

 as July, but most reach maturity at the end of June, they then fall 

 to the ground and pupate in the soil.

THE MARCH MOTH. 



(Anisopteryx ccscularia. Schiff.) 



This is another member of the wingless female group. Although 

 not so generally reported as a 

 nuisance, it now and again does 

 considerable harm to the apple, 

 and has also been sent by corre- 

 spondents from Surrey on the plum 

 and pear. Its normal food plants 

 are the whitethorn and blackthorn ; 

 it also infests the oak, lime, elm, 

 maple and walnut, and a few may 

 be taken on the Spanish chestnut. 

 It occurs over a wide area from 

 Scotland downwards, and has been 

 reported as a fruit pest from Here- 

 fordshire, Yorkshire, Sussex, Kent 

 and Middlesex. I have also seen 

 it in abundance on plums in
