TREATMENT 



can only be of very doubtful benefit, as the larvre are difficult to 

 get at, but it is said that a sticky dressing smeared up the trunks 

 in May easily checks the egress of the moths, and prevents further 

 egg-laying.

THE LAPPET MOTH. 

 (Lasiocampa quercifolia. Linn.) 



This is another handsome moth which now and again is sent 

 by orchardists, owing to its large and strange caterpillars devouring 

 such quantities of foliage. Fortunately, it is not very common and 

 certainly cannot be looked upon as a pest. The quaint and active 

 pupre in the cocoons 

 are also frequently sent. 

 Xumbers have been 

 brought me by hedge- 

 trimmers who have 

 noticed them moving, 

 and taken them for 

 mice, the mouse-coloured 

 cocoon having led to this 

 mistake. The ravenous 

 larva' destroy the leaves 

 of apple and plum in 

 orchards and gardens, 

 often stripping whole 

 shoots and boughs. 



Miss Ormerod refers 

 to it (1), but I know of 

 no other record of it as 

 causing annoyance. It 



occurs fairly commonly over the Midlands, eastern, western and 

 southern counties of England.
