color is ash-gray; the fore-wings are sprinkled more or less 
with black scales, and have on the apical edge at the base of 
the fringe six to seven equidistant black dots. On the disk 
are also four larger black or brown dots, two before and 
two behind the middle, the latter nearer together than the 
former. The moth is shown in Fig. 228. 
There are two other species of Palmer Worms, both 
found occasionally in our orchards. These are the Com- 
rade Plum Worm (Ypsolophus contubernalellus Fitch), and 
the Striped Palmer Worm ( Y. malifoliellus Fitch). 
In case these worms should become numerous they can 
be successively combatted by spraying the trees with any of 
the arsenical poisons; they are also readily dislodged by the 
use of whale-oil soap diluted with water. 
THE STRAWBERRY ROOT-BORER. 
(Anarsia lineatella Zell.). 
This insect is not found alone on the strawberry plant, 
but is also very destructive to the twigs of a number of 
trees. In the Eastern States it has the bad habit of boring 
into the tender twigs of the peach tree, killing the terminal 
buds, and in the western states it invades the young plum 
trees ina similar way. In Europe it is also destructive to 
the peach. It is an insect that can become very destructive 
to the strawberry plants. Its caterpillar is only about half 
an inch long, reddish-pink, fading into dull yellow on the 
second and third segments; the cervical-shield is smooth, 
horny, and of the same brownish-yellow color as the head. 
A few shining and reddish dots are found on each segment, 
from each of which rises a single, fine, yellowish hair. The 
under surface of the worm is paler. It bores irregular chan- 
nels through the crown of the plant, sometimes excavating 
large chambers; at other times it tunnels it in various 
directions. If we examine such cavites or tunnels in spring
