REARING BEETLl 



the two ha] ether with a strong rubber band. Slightly 



moisten the wood in the l>"\ twice a week, and if the larva 

 escapes by boring a hole through the wood, replace it in 

 the central cavity by filling the hole with a plug. Mr. 

 Siewers raised the larvae of borers in tin or % i wet 



hard-wood or poplar sawdust : he kept them for six or eight 

 months, changing .the sawdust once a month. 



rtain larvae, especially those of Lamellicorns and Ela- 

 teridae, before transformation enter the earth. For such 

 species place some earth in the box, but not before the 

 larvae Bhow a decided wish to go there by quickly boring 

 holes straight downwards: for the earth in contact with the 

 moist wot '1 rapidly forms a deadly fungus. Of course the 

 earth for the breeding-boxes musl 1"- thoroughly baked, so 

 as to destroy all insects, etc., destructive to the helpless 

 soft-skinned pupae ; the larvae and pupae Bhould also be 

 kept in darkn< 



Rearing of Bark and Bast-boring Beetles. Such insects, 

 especially Longicorns, Buprestids, Scolytidae, • . . may be 

 reared by cutting oul with the .-aw ami hatchet pieci 

 the infested tree, with the bark on, about six inches square 

 and one inch thick. The castings and sawdust, together 

 with the larva', should be placed under the hark. Si 

 pieces of bark tied together with the bast sides opposite 

 will sometimes answer the purpose, but the better way is 

 to leave the larvae in the w 1 until they are nearly full- 

 grown; then, in general, the transformations are compl 

 in about two weeks 



Rearing Larvae of Dung beetles. — These may be taken 

 home with a part of the earth above which they live and 

 part of the nearly dried and inodorous cow-droppingfl under 

 which they hide. "But here the urea - ' • to be 



taken nol to overlook the very numerous small Staphylinidae 

 and carabidous larva' that live with — or rather on — those 

 scarabaeidous larvae." *
