very hairy. The larva lives about a year, and the beetle feeds largely on 

 the foliage of fruit-trees and Hoses. Being a day-flier, and very active in 

 the sunshine, it must be attacked late in the day or when the weather is 

 dull. 



The Hose Chafer (Cetonia aurata) is a handsome beetle about '-\ in. long, 

 with golden green wing-cases marked with transverse creamy spots, and 

 the body coppery beneath. The larvae live underground for two or three 

 years, eating the rootlets of Rose-trees, and gnawing off the skin of the 

 larger roots. The adult beetles feed largely on the anthers and petals of 

 Roses. They are most easily collected on dewy mornings, when they are 

 sluggish, or at night. 



The Pine Beetle (Hylesinus (Hylurgus) piniperda) is one of the most 

 destructive of forest insects. The mature beetle is about 1 in. long, of 

 a dark brown to glossy black colour, thinly covered with brown hairs 

 springing from little tubercles, which, on the elytra, are disposed in rows 

 between lines of punctures. Eggs are laid in March and April in the thick 

 rough bark of recently felled trees, especially Scots Pine and Black Austrian 

 Pine. The female lays about 100 eggs, which produce larva? in about a 

 fortnight. The larva? feed on the bast or inner bark. The young beetles 

 appear in June and July, and then usually bore into the young shoots 

 of Pines about 2 ins. beneath the terminal bud, and, tunnelling upwards, 

 cause the death of the shoots. The best method of prevention consists of 

 leaving autumn or winter felled trees in or near the wood, in order to 

 attract the beetles in the breeding season, and then removing the bark 

 during May, when the larva? may be destroyed by exposure. 



The Spruce-bark Beetle (Bostrichus {Tomims) typographies) and others 

 of the genus destroy Fir-trees by tunnelling just below the bark. As a rule 

 they attack sickly trees, but may extend their depredations to healthy 

 specimens also. Prevention consists of the timely removal of sickly or 

 uprooted trees, and in stripping the bark from logs left lying in the woods 

 over summer.
