Injuring the Acorns. 



20. The Acorn Weevil, Balaninus rectus, Say. Order Coleoptera ; Family 



CURCULIONIDAE. 



The larva of this beetle lives in the acorns of the red (and probably other kinds of) 

 oak ; it is a short, stout, footless grub, of a whitish color. In the fall, by which time it 

 is full grown, it cuts a circular hole in the side of the acorn, through which it escapes ; it 

 then burrows in the earth, emerging the following season as a small, long-snouted, brownish 

 beetle, obscurely mottled with spots of a lighter color. Common in Canada. 



21. The Acorn Moth, Holcocera glanduella, Riley. Order Lepidoptera ; Family 

 Tineidae. 



The acorns that have been deserted by the weevil are selected by this little moth as 

 a fitting abode for her offspring, and the little hole so nicely cut by the grub of the beetle 

 provides her with a convenient opening, by means of which she is able to deposit an egg 

 within the acorn. From this egg hatches a tiny, slender, grayish-white caterpillar, with 

 a light brown head, and blue-black marks on the upper surface. The moth is silvery gray, 

 marked with reddish brown ; the hind wings darker grayish brown.
