It was found that the neighbourhood of the solitary mole run 

 which could be found in the infested area was practically free from 

 injury (Warburton).

THE STRAWBERRY LEAF BEETLE. 

 (Gfalerucetta tenclla. Linn.) 



This again, like the Leaf Moth, has only been once recorded as 

 doing any harm. Ormerod (1) received information of the damage 

 done by it from Hundred Acres, Wickham, Hampshire, with a note 

 that they were destroying the straw- 

 berry plants in the neighbourhood, and 

 that it was considered a new pest in 

 the locality. 



This beetle is fairly common in this 

 country on willows, alders, etc. In 

 German yKaltenbach (2) records it from 

 the Meadow Sweet (Spiraea ulmaria) 

 and the Silver Weed (Potentilla, 

 anserina). The beetles of this genus, 

 several of which are harmful to forest 

 trees, feed in both larval and adult 

 stages upon the leaves. There they 

 do damage in two ways. The larvse 

 eat the lower or upper skin and 

 soft underlying tissues, leaving the 

 epidermis below them intact, like the 

 pear slugworm ; the leaves then present a curious spotted appearance. 

 The adults eat out irregular holes right through the leaves. 



The beetles and larvw may be found together in July. The 

 former are about \ inch long, dull yellow to pale brownish ; the head 

 is yellow with a broad black stripe across it ; the thorax is yellowish 

 with a dark central furrow and a small round depression on each side
