VARIOUS ENEMIES OF ROSES. 79 
that operate similarly, should be searched for in the bound 
and rolled leaves. Or the bushes may be sprayed with Paris 
Green (see page 84). 
Leaf-eating Caterpillars. 
One of the most troublesome of these is Emphytus cinctus, 
which feeds upon the edges of the leaves. It may be cleared 
off by handpicking, or Paris Green may be applied. 
Stem-boring Grub. 
The larva of Pecilosoma candidatum is happily not a 
common enemy, for his method of attack is insidious. He eats 
his way into the young shoots. These may be cut off and 
burnt, but converting the grub into ashes does not altogether 
compensate for the loss of promising shoots. 
Rose Caddice Fly. 
The larva of Lyda inanita forms for himself a comfortable home 
by spirally arranging fragments of Rose leaves. Housing 
plans of this sort should be foiled by a vigorous pressure. 
Leaf-cutter Bee. 
The grower sometimes finds holes in otherwise sound and 
healthy leaves, cut with remarkable evenness. These are the 
work of the leaf-cutter bee, Magichile centuncularis. She uses 
the parts removed for lining her nest. Unless her operations 
are very extensive little harm is done; if they become de- 
structive, the bee or her nest must be sought for and destroyed. 
Aphis or Fly. 
Greenfly is a great enemy of Roses, especially in a dry 
spring. In the absence of heavy rain a vigorous hosing is 
advisable. Or the bushes may be sprayed with soaparite. 
Rose Bedeguar. 
This is a curious moss-like growth, in reality a gall, pro- 
tecting the larve of the fly Rhodites Rose. It is not usually 
present in dangerous numbers, but may be cut off to prevent 
spreading. . 
Red Spider. 
This does not, as a rule, trouble Roses very much, but 
is apt to cause damage when the plants are suffering from 
drought, especially in the case of Crimson Rambler. Growers 
of this Rose should avoid shallow, hungry soils in dry positions. 
Moisture, which encourages vigorous, healthy growth, will 
keep red spider at bay.
