164 FRUIT CULTURE. 



with dirty white, and having many transverse black lines. 

 The hind wings are dingy brown. The insects come forth 

 in June or July, and the females lay their eggs in crevices 

 of the bark of the same or other trees. 



REMEDIES. Many of the larvae may be removed by 

 means of a cane or piece of wire bent at the end and 

 thrust into their large burrows. Soap-suds, forcibly 

 injected by means of a syringe or garden engine, will 

 kill the grubs or render their food useless. Tobacco 

 smoke, and the fumes of burning sulphur are also suc- 

 cessfully employed for the destruction of the enemy, by 

 blowing them into the holes. Should the moths be very 

 prevalent, the females may be deterred from laying their 

 eggs on the trees by painting the trunks in June and 

 July with a mixture of clay and cow-dung. The perfect 

 moth is sluggish during the day, and may readily be 

 destroyed when detected. 



THE WOOD LEOPARD MOTH (Zeuzera esculi). The 

 popular name refers to the spotted wings of the insect. 

 The male measures about Ifin. and the female 2|- in. or 

 nearly 3 in. across the wings. The fore ones are white 

 with greenish-yellow veins, and richly spotted with 

 bluish-black ; the markings of the hind wings are fainter. 

 The" caterpillars are pale yellow, or whitish, with a 

 few black spots and numerous small dots of the same 

 hue. They burrow into the stems of various fruit trees, 

 including the apple, pear, plum, and hazel. The damage 

 they do is similar to that of the goat moth, than which 

 they are smaller. The females lay their eggs in crevices 

 oE the bark during July and August, and the larvte are 

 hatched out in a few days, feeding at first on the bark, 

 but afterwards burrowing into the stc-ms, in which they 

 live for one year, or two according to some naturalists;
