the outside of the tent or along tlie branches. They are sornewliat 

 timid and fall to the ground on the tree lieiiig shaken, Imt soon 

 crawl hack to the fulia^e a"ain. 



ilaturity is reached from the middle of June to the end of July, 

 when they disperse and spin cocoons of loose pale silk ; mixed with 

 it are a numher of hairs and a yellowish powder. 



The cocoons may lie spun singly amongst the leaves, or on 

 fences, etc., or, as seen in Fig. 20, a mass of them together. In the 

 cocoon the larva clianges to a dark brown pupa, from which tlie moth 

 hatches in t\\o or three weeks. 



The food plants are very varied, such as oak, elm, liawthorn and 

 roses being tlieir favourites, 



besides the fruit trees men- '

;Many of the egg bands are 

 naturally cut off by pruning, 

 and these of course should be 

 burnt. As the egg Ijands are 

 readily seeir, it would lie 

 advisable after an attack of 

 Lackey iloth to go over the 

 plantation and see that all of 

 them are destroyed in winter. 

 Spraying with arsenical fl'ashes 

 has been found of great bene- 

 fit, and the early destruction 

 of tents should always be 

 seen to. For this we can use 



long-handled pruners, and care should be taken to see that all the 

 caterpillars are destroyed. Where large trees are a^ttacked and 

 spraying is not possible, an excellent plan is to have the larv;e 

 shaken down. Thick grease bands placed around the trunks of the 

 trees •will stop those which are not killed on the ground from 

 ascending again. 



KvTuitAL Enemies. 



No insect parasites are of any value in checking the Lackey 

 Moth. Of birds the only one that seems to feed upon tlie caterpillars 

 is the Cuckoc), which is well known to feed on hairy larvte.
