of Tenthredo testudinea upon young apples, devouring the interior of 

 the fruit, being the only instance yet known of such habits amongst 

 the Tenthredinidce, although the larvae of Nematus intercus and some 

 allied species inhabit the interior of galls upon willow-leaves, upon 

 the substance of which they subsist. The larvae of the former insect 

 emit a very powerful scent, similar to that of the bed-bug, and quit 

 the apple as soon as it is fallen to the ground, in order to undergo 

 their transformations in the earth, the eggs being deposited on the 

 young fruit whilst the trees are yet in flower.
