How the Pest may be Detected. 
The presence of this fruit pest may be detected by the early 
destruction of the developing buds, which on partly opening are seen 
to be eaten and shrivelled and which soon turn brown ; these buds 
will be found to contain a small reddish-brown caterpillar, the cause 
of the injury. Later the damage is still more noticeable, the opening 
leaf and blossom being spun together, for both leaf and blossom buds 
are attacked. There may frequently be noticed a gummy appearance 
of the opening leaflets. The larva enters the bud, if it has not 
already burst, by eating down between the bracts, and there, as 
described by Kollar, a drop of sap forms which tends to hold the bud 
intact and to stop it from bursting ; in any case if it does open the 
young leaves soon shrivel and turn brown. During the past summer, 
trees, especially cherry, have been quite ruined in this way. More 
usually, many of the buds fully open, leaf and blossom appearing as 
usual, the caterpillars later spinning the bunches of leaves and 
blossoms into a mass with silk. These leaf nests frequently die right 
away and turn brown in a very characteristic manner. Slingerland 
states that in America the larvse also sometimes “ burrow down the 
stalk for two or three inches, causing it to die.” This habit lias not 
so far been observed in England ; in all cases the larva boring down 
the top shoots of apple and pear has proved to be that of the Pith 
Moth ( Laverna atra) {vide p. 68). When nearly mature the Bud 
Moth larva forms more or less of a tube by rolling up a leaf and 
roughly lines it with loose silk. The caterpillar at first only uses 
this tube as a shelter from which it emerges to feed, gradually 
drawing the neighbouring leaves together by silken cords. From
