226 DISEASES AND ENEMIES OF BEES. 
taking up any eggs on their feet, if this should happen to 
be the method by which they get among the combs of a 
populous stock. They are often detected there, and I 
can conceive of no other means by which they can be de- 
posited. A worm lodged in the comb makes his way 
either to the center, or between the heads of the young 
bees in the cells and 
the sealing, and as he 
proceeds, eats a pas- 
sage, lining it with a 
shroud of silk, and 
gradually enlarging 
it, as he increases in size, as shown in fig. 90. When 
combs are filled with honey, they work on the surface, 
eating only the sealing. In very weak families, this silken 
passage (fig. 91) is left untouched, but is usually re- 
moved by all strong colonies. 
When a worm is in the center of a comb filled with 
brood, its passage is not at first discovered. The bees, to 
get it out, must bite away half the thickness of the comb, 
removing the brood in one or two rows of cells, sometimes 
for several inches. This will account for the number of 
immature bees often found in the spring on the floor- 
board at morning ; as well as in stocks but partially pro- 
tected after the swarming season.

DEVELOPMENT OF THE LARVZ. 
When undisturbed, the larvee will grow one-half or two- 
thirds larger than when their right to the comb is dis- 
puted. In one case they often E 
make their growth, and actu- 
ally wind up in their cocoon, 
when less than an inch in chi 
length ; in the other, they will Sig Oe ae 
quietly fatten until they are an inch and a half long, and 
as large as a pipe-stem (fig. 92.) When first hatched
