with earth, makes it almost impossible for 
any one to distinguish them from the earth in 
which they are concealed, unless they are previ- 
ously acquainted with their form and appearance. 
They remain about four or five weeks undergoing 
the formation of the perfect insect. 
In form, beauty, and activity, nature has 
displayed a wonderful change. The animal which 
once existed so ravenous, and so much the terror 
to the Horticulturist, and recently quite inactive, 
is now an active beautiful four-winged Fly, and 
of itself quite harmless ; but not many weeks 
elapses before its descendants pursue the same 
ravenous course their parents did in the first stage 
of its existence ; and these also, when nature calls 
them to retire for the purpose of going through 
the different processes, like their predecessors, retire 
into the earth, where they spend the dreary 
months of winter in the before described cell ; and 
although the frost should be intense, or the wea- 
ther wet, yet their protection is so substantial 
that we find they survive ; and early in the spring', 
about the latter end of March or beginning of 
April, they emerge from their case to embrace 
that reviving period. 
The body of the Fly is small, and about 
two-thirds the length of its wings ; the greatest 
substance or thickness is the thorax or breast, 
where the legs are inserted ; the abdomen gra- 
dually diminishing downwards to a point. It is fur- 
nished with six legs; a very small head, eyes.
