The full-grown larva spins a silken cocoon in which the insect trans- 
forms to a reddish-brown pupa. Later the parent moth emerges from 
the pupa. During warm weather, the Mediterranean flour moth re- 
quires about nine weeks to pass through its egg, larva, and pupa 
stages. A more complete discussion of this pest will be found in 
Bulletin 872 of the United 
States Department of Agri- 
culture, “ Insect Control in 
Flour Mills.” 
MEAL SNOUT MOTH." 
The meal snout moth is 
brownish in color, some- 
what larger than the In- 
dian meal moth, though 
varying in size, usually 
having.a wing spread of 
about one inch. Its fore- 
wings are marked ina 
characteristic pattern indi- 
cated in figures 31 and 32; 
they are hght brown with 
dark brown patches at base 
and tip and each with two 
wavy transverse white 
lines. The meal snout 
: moth is widely distributed

attracts much attention 
because of its capacity to web up and bind together seeds of various 
kinds. The larvee are whitish and attain a length when full grown 
of about one inch. The two larger larve of figure 31 indicate the nor- 
inal shape and show the contrast between the black of the head and 
the first body segment and the white of the remainder of the body. 
Often the body of the larva is tinged with orange toward each end. 
The larve spin peculiar tubes of silk and particles of the food ma- 
terial. They rest in these tubes, which are very tough, and feed 
from the openings at the ends. When full grown the larve leave 
the tubes, spin silken cocoons, often covered with food particles, 
and transform to the pupe from which later emerge the adult moths.
