The Wood Leopard Moth.—a, b, larvæ; c, male moth; d, female 
moth; e, larval burrow. All natural size. 
“ The eggs are laid by the female moth on the branches, probably 
placed just into the bark, and the young larve bore at once into the 
wood, usually at the crotch of a small branch, or at a node, and work 
downward, sometimes just under the bark, sometimes in the solid 
wood. They grow apace and get into larger branches, still working 
downward as a whole, but often varying in course; sometimes making 
it circular, so as to girdle the stick they feed in. For at least two 
years they feed, rarely emerging from the burrow, though they do 
occasionally come out for the purpose of changing their quarters and 
beginning their destructive work elsewhere. Then they change to 
somewhat slender, brown pups, and these wriggle themselves through 
the bark in due season, and soon after the moths emerge.” 
The moths, fortunately, are attracted to electric lights, and large 
numbers of them are thus destroyed. The larvæ may be destroyed by 
pouring a little bisulphide of carbon in the burrows and then plugging 
the outer openings of the latter with putty.
