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. 
Genus TRICHOPHAGA Ragonot 
(i) Trichophaga tapetzella Linnaeus. (The Carpet-moth.) 
The nature and habits of this species are very closely allied to 
those of the last two species of which we have spoken. Like 
them, it was originally intro¬ 
duced into America from the 
Old World. It differs from 
them in the larval state in 
that, instead of simply mak¬ 
ing a cocoon for itself out of 
bits of hair as the Clothes- 
moth, or forming a movable 
case for itself as the Fur- 
moth, it weaves together, out of the debris of the material in which 
it is carrying on its ravages, long galleries lined inside with strands 
of silk. These long, tortuousgalleries, cutthroughthepileof carpets, 
are familiar objects to the careful housewife, whose horror and anx¬ 
iety have often been expressed to the writer. It is one of the sad 
prerogatives of the entomologist to be made from time to time 
the recipient of the household woes of his neighbors, who dis¬ 
cover that the moth and the buffalo-bug “corrupt,” and that the 
white ant and the cockroach “steal.” 
The perfect insect, as shown in the annexed cut, is in appear¬ 
ance a very different moth from either of the foregoing species. 
CLOTHES-MOTHS 
“ The moth shall eat them up like a garment, and the worm shall eat them like 
wool.” Isaiah.—li, 8. 
From the accounts which have been given in the preceding 
pages of the three species of Clothes-moths, the ravages of which 
are commonly encountered in the household, it has been learned 
that they may each be discriminated from the other by the habits 
of the larvae. The Carpet-moth makes a gallery of the substance
