The Frog. — This animal undoubtedly destroys large numbers of 

 the beetle, at the time when their destruction would be of the 

 greatest benefit, during the night of their emerging from the 

 ground and before they have deposited their eggs. Dr. Hoy, of 

 Racine, Wis., relates that on the twelfth of June, having occasion 

 to go across a little piece of prairie, he saw a large spotted frog, 



Bona , very large and hardly able to jump. He captured and 



opened him, and to his surprise found within him eight May- 

 beetles. Others were caught and examined, and each was found 

 to contain from one to four of the beetles (Trans. Wise. St. 

 Agricul Soc, xix, 1881, p. 297). 



Other Mammals. — Among the mammals appointed to check the 

 ravages of the cockchafer and allied leaf -beetles in Europe, accord- 

 ing to Latreille, are the badger, weasel, marten, bats, and rats. 

 The same animals, no doubt, render more or less service in 

 restricting the increase of the May-bug in this country. 



Domestic Foivls. — If these be watched as they follow the plow 

 in our gardens and fields in search of such insects as may be 

 brought to the surface, it will be seen that they show a special 

 fondness for the white grub. Their presence during the operation 

 of plowing should, therefore, always be encouraged. 



The Crow. — The common crow feeds upon both the beetle and 

 the grub. It is believed by many that its frequent occurrence in 

 corn-fields is the result of its fondness for the grub, which is prey- 

 ing upon the young corn, rather than for the corn itself. The 

 studies that have been so ably conducted during the last few years 

 upon the food of birds should have settled ere this the question 

 beyond all doubt, whether the crow is to be driven from, or invited 

 to, our corn-fields. 



Mr. Glover states that this bird has been observed to return on 

 the appearance of the dor bug or May-beetle, and to feed greedily 

 upon it both in its winged and larval stages. 



Other Birds. — The beetles have been found in the stomach of 

 the king-bird, Tyrannus Carolinensis, shot in the month of May. 

 The robin, black-birds and jays are also said to feed upon them. 



The grub has been taken from the stomach of thu sparrow 

 hawk, Falco sparverius. 



Insects. — The grub has also enemies among its own class, which 

 prey upon it. Several of the predaceous beetles are said to
