APRIL 



OVA] 



This is the month when many hibernating species deposit their ova, as well 

 as several which are freshly emerged. Owing to the scarcity of leaves upon 

 the trees and bushes, the egg in many cases may be more readily found than 

 when, later in the season, the branches are more covered. Some day-flyer, 



" Drawn from his refuge in some lonely elm, 

 That age or injury has hollowed deep," 



may sometimes be seen, when the sun shines, engaged in the interesting 

 operation of oviposition. By carefully watching, a clue as to the plant upon 

 which the egg is laid, as well as its situation, will be often afforded.
