Frnit trees and Ijushes are tre(iuentl}' seriously damaged by Ked 

 Spiders, the leaves lieing attacked just as in hops, Eed Spiders are 

 also very harmful under glass. TetrcmycJius tdaruis is one of the 

 most serious pests in vineries ; melons and cucumbers are similarly 

 attacked by T.cuaiy)ucris. The ditfercnt species can only be identified 

 by specialists. They have very similar hal)its, however, and may 

 be killed l»y the same wash. 



Tlie Eed Spiders of fruit trees belong to two genera, Bnjohia ami 

 Tennipalims. The former are most destructive, especially to the 

 gooseberry and currant. 



The commonest species {B. speciosa) is found on the ivy, and 

 invades the fruit bushes from these centres. 



These Brijohla Mites have very long front legs, and spin but a 

 scanty webbing. The Brjjohias hibernate as adults, not in the egg 

 state, as previously supposed. The eggs of the Tomijm/pvs may be 

 found on the bushes all tlie winter. When present in numbers, the 

 Mites soon cause the leaves to become unhealthy and fall off. 



The colour of the Bn/ohirc is invariably like that of the Red 

 Spider on hops, chiefly various shades ol" grey, green and red, darkened 

 at the sides. They are active from March onwards, and lay eggs in 

 May and June. The eggs are placed in the axils of twigs, and 

 between the remains of old bud scales. 



The genus l^nuipcdpus live tm plants in a similar way, but 

 their work is not so evident. The common species {i^pinosus) is 

 very bright red, and the legs are shorter than in Brtjohia. The 

 bright red eggs are very noticeable and occur on the trees all the 

 winter. 



The larvie or young of all the Mites are six-legged. 



Strawberry Beetles. 



An en([uiry from Xorfolk was sent to the Board regarding beetles 

 attacking strawberries. 



Several species of Ground Beetles attack strawberries, including 

 the following : — Haipalits ruficoniis, Fabr. ; OmaHCUs cid<jo/ris, Linn. ; 

 Stcropua madidus and Galathus clddoidcs, I'anzer. 



These beetles attack the berries at night, usually just wdieu the 



* Tlie Hop Red Spider is now kiiuwii tu be Tetranychus aUIuem. It is also 

 fouud on Hollyhock and French Beans. It is larger than T. tehtrias, greeuisli- 

 brown, the lemales becoming red from Augusl to tlie following wpriug.
