The moth is widely spread over Britain. I k'now of no records ot 

 it having cansed serious damage.

THE RED PLUM MAGGOT. 



( ( liiiidiii j'li IK hnniii. Tl'.) 



This is a well-kmiwn inseel, entomologically, but fruit-i^rowers 



seem to pay little attention ti:> it. Stainton says : " In the caterpillar 



state it is exceedingly plentiful in plum 



pies." 



(_)ne dues not like finding these little 



catei'pillars, as freijuently hajipens in 



the West of Kngland, in plum and 



damson tarts, and their presence in 



bottled fruits, as was reported frdtn tlie 



Horticultural College, Swanley (1), is 



just as bad, and would materially lessen 



the market value. 



In 1894 it occurred in some numbers 



in jilums at Kingston-on-Thames (l!), 



many larva' lieing obtained on the l.lth 



of August. The plums fell before thrj 



were fp_iite ripe, one tree lost all the cr(.ip. 



On examining the fruit, a. hole at the base of the plum near the stalk 



is noticeable, and on opening the fruit, the centre is seen to be 



damaged, and there is much \\-et 

 " frass," together witli the reddish 

 caterpilku'. They live inside the 

 plum aromid the stone, tunnel- 

 ling here and there into the 

 Hesh. 



The damage done liy the 

 maggots to tile fresh fruit is not 

 so easy to detect, espetaally in 

 damsons. 



Very frei|uently, in fact, in 

 the majority of cases, the fruit 



does not fall, and hence the larva' get liottled with thi_' fruit and get 



into pies, etc.
