Fur-moth

Fur-moth (detail)

This insect makes for itself a movable case in which it travels about in the larval stage. Its food is very much the same as that of the preceding species, and it is equally destructive. The moth differs from the pale-colored Clothes-moth in having the fore wings darker. They are, in fact, quite gray, mottled with darker gray, as shown in the cut which we have herewith caused to be reproduced. A comparison between the figures of this and the succeeding species will enable the student to readily discriminate them. The lower left-hand figure gives a good representation of the case made out of bits of hair in which the caterpillar performs its migrations. The insect is many-brooded, according to the temperature of its domicile. In the warmer parts of the country the processes of generation no doubt go on continuously.

In the colder parts of the country winter arrests development temporarily.

The insect is widely distributed all over the continent, and in fact all over the world.
