JUNE BUGS, COCKCHAFERS. 



Hoplia. Adults are usually found on flowers during 

 the day. The two sexes often differ in size and color. 



Dichelonycha. Adults are usually found on leaves of 

 trees and shrubs. The eyes are rather large and promi- 

 nent. The antennal club of males is nearly as long as the 

 rest of the antenna. 



Macrodactylus The name means " lon g fingered" and 

 all who grow roses will agree that it fits, 

 in both a literal and a figurative sense. There is little 

 you can do to combat this pest unless you wish either 

 to keep your roses, flowers and all, sprayed with poison 

 when the beetles are around or to plow deeply your lawn 

 and the lawns of all your neighbors every winter in order 

 to turn the young of these Rose Beetles out into the cold. 

 It is of some help to go out several times a day and knock 

 the adults which have made their appearance in the 

 intervals into a cup of kerosene. It is said that chickens 

 die from eating them. The Rose Beetle (Plate LXXX) 

 also feeds on grape blossoms. Its specific name is sub- 

 spinosus. A much less common species, angustatus, also 

 occurs. It is more southern in its distribution and confines 

 its attentions chiefly to oak and other wild plants. The 

 specific distinctions are slight and technical. 



Phyllophaga These (Plate LXXX) are the beetles 



that buzz and bang about the room in the 

 early summer evenings, usually going under the name of 

 Lachnosterna. There are numerous species but distinguish- 

 ing them is a matter of considerable difficulty. The female 

 is said to deposit her eggs, enclosed in a ball of earth, among 

 the roots of grass. The larvae are "white grubs"; they 

 get to be about as thick as a man's little finger and are 

 frequently very injurious to the roots of various plants. 

 Cases have been reported in which they were so numerous in 

 lawns that they had completely cut the roots; the turf 

 could be rolled up like a carpet. The larval stage of some 

 species, at least, lasts for two or three years. Pupation 

 occurs in an underground cell.
