The larva of this moth constructs no case, but spins a silky. or more 
properly cobwebby, path wherever it goes. When full grown it builds a 
cocoon of silk, intermixed with bits of wool, resembling somewhat the 
case of pellionella, but more irregular in outline. Within this it under- 
goes its transformation to the chrysalis, and the moth in emerging 
leaves its pupal shell projecting out of the cocoon as with the preceding 
species. 
THE TAPESTRY MOTH. 
The tapestry moth (Trichophaga tapetzella L.) (fig. 3) is rare in 
the United States. It is much larger than either of the other two 
species, measuring three-fourths inch in expansion of wings, and is 
more striking in coloration. The 
head is white, the basal third of 
the forewings black, with the ex- 
terior two-thirds of a creamy white, 
more or less obscured on the mid- 
dle with gray; the hind wings are 
pale gray. 
This moth normally affects rather FiG. 3.—Trichophaga tapetzella: Adult moth. En-

smaller species and is more apt to occur in carpets, horse blankets, and 
tapestries than in the finer and thinner woolen fabrics. It also affects felt- 
ing, furs, and skins, and is a common source of damage to the woolen 
upholstering of carriages, being rather more likely to occur in carriage 
houses and barns thanin dwelling houses. Its larva enters directly into the 
material which it infests, constructing burrows or galleries, which it lines 
more or less completely with silk. Within these galleries it is protected 
and concealed during its larval life, and later undergoes its transforma- 
tions without other protection than that afforded by the gallery. The 
damage is due as much or more to its burrowing than to the actual 
amount of the material consumed for food. 
One of the parasites reared from pellionella (Apanteles carpatus Say) 
has also been reared from this species at St. Louis, Mo. 
REMEDIES. 
There is no easy method of preventing the damage done by clothes 
moths, and to maintain the integrity of woolens or other materials 
which they are likely to attack demands constant vigilance, with fre- 
quent inspection and treatment. In general, they are likely to affect 
injuriously only articles which are put away and left undisturbed for 
some little time. Articles in daily or weekly use, and apartments fre- 
quently aired and swept, or used as living rooms, are not apt to be 
seriously affected. Carpets under these conditions are rarely attacked, 
except sometimes around the borders, where the insects are not so much
