The Twig-pruner 



Elaphidion villosmn Fabricius 



In early autumn an orchardist's attention may be attracted 

 to twigs or branches from a few inches to two or three feet in 

 length which have fallen to the ground, having been deftly 

 pruned from the trees by this twig-pruner. An examination 

 of the severed end of the branch will reveal a smoothly cut 

 surface, near the center of which is an oval opening plugged 

 with a wad of fine shavings and sawdust. If the branch be 

 split open, it will usually be found to have been tunneled, often 

 from 10 to 15 inches, by a slender, whitish grub nearly j of an 

 inch in length, then lying in the tunnel near the severed end, or 

 the insect may have already reached the pupal or even the 

 adult or beetle stage. The grub is quite hairy, and it has three 

 pairs of minute legs. Usually the grubs transform in the 

 spring and the beetles continue to emerge from June till Sep- 

 tember. This Cerambycid beetle is a slender, reddish-brown 

 insect rather sparsely covered with yellowish, somewhat mottled 

 pubescence. It varies considerably in shape and size, measur-

 female a httle shorter and those of the male longer than the 

 body. The proximal joints of the antennae are armed with small 

 spines, and each wing-cover terminates in two small spines. 



The eggs are inserted in the smaller twigs of living trees in 

 summer. The young grub hatching therefrom feeds for a
