Austria in 1776. The popular name — eye-spotted bud moth — 

 first loused by Dr. Harris in 1841, is now in common use. The 

 moth lias been described under five different names, and has been 

 placed in six different genera. The genus Tmetocera ("cut- 

 horned," from the notched appearance of the base of the antennae 

 of the male moth) was established in 1859 for the reception of this 

 insect which still remains its only representative. 



How Its Presence is Indicated. 



The caterpillars of the bud moth are astir early in the spring, 

 usually about May 1st, and soon begin their destructive work on 

 the swelling and opening fruit and leaf buds. They eat into the 

 buds, and often so check and disfigure a small tree as to spoil its 

 symmetry. More often the caterpillar does not begin its work 

 until the buds are nearly half opened. It then feeds upon th« 

 central expanding leaves or flowers, tying them together with 

 silken threads (see the frontispiece, and figure 32). Some of the 

 partly eaten leaves soon turn brown and thus render the work of 

 the insect quite conspicuous; one correspondent wrote that his 

 trees looked as though a fire had swept quickly through them, as 

 so many leaves had turned brown. This tying together of the 

 opening leaves and flowers and the brown appearance of many of 

 them, are the most characteristic indications of the presence of the 

 insect. 



Its Appearance. 



The caterpillar. — It is in this stage that this insect is familiar to 

 fruit-growers. It appears on the buds in the spring as a little 



brown caterpillar, about .IG of an inch 

 long, with a black head and thoracic 

 shield. In June, when the caterpillars 

 are full-grown (Fig. 33) they are about
