THE BUFF-TIP MOTH. 



{Phalcra liuccpluda. Stephens.) 



Inquiries have frequently been made during the autumn months 

 concerning the larvpe of the Buff-tip Moth {Phalcra hucej^hala). 

 These caterpillars very frequently occasion a great deal of harm to 

 the leafage of the elm, lime, beech, birch, nut, sallow, rose and oak. 

 Fruit trees are also sometimes attacked. .Frequent reports come to 

 hand of their ravages on rose, elm and lime trees in and around 

 London, and also in nut plantations in Kent. Mr. F. Smith of 

 Loddington finds them in his nut plantations and Mr. Buley of 

 Woodnesborough found them attacking cobs and filberts. In 

 the same year I found them defoliating cobs at Wye and they 

 were also reported from S. Devon and elsewhere. Ptecently they 

 have been causing some alarm in cherry orchards (1), Mr. Lewis 

 Levy wrote in 1906 from Borden Hall, Sittingbourne, in August, 

 saying : " We have had several cherry trees whose leaves have been 

 almost devoured by the caterpillars. Over one hundred, I should say, 

 on one tree." The moth (Fig. 195) is common and very generally 

 distributed over Great Britain and generally attracts attention on 

 account of its peculiar and beautiful appearance, whilst the large size 

 of the caterpillars, and the havoc they cause, render them particularly 

 conspicuous objects. The eggs are also often sent with inquiries as to 

 their nature.
