CHAPTER ir. 
THE CRUSTACEANS AND INSECTS.* 
BY A. S. PACKARD, JR. 
Representatives. of all the grand divisions of the Insects and 
Crustaceans have been found in this cave, and if no worms have 
yet been detected, one or more species would undoubtedly reward 
a thorough search. 
We will enumerate what have been found, beginning with the 
higher forms. No Hymenoptera (bees, wasps, and ants) or Lepi- 
doptera (moths) are yet recorded as being peculiar to caves. The 
Diptera (flies) are represented by t.wo species, one of Anthomyia 
(Fig. 122) or a closely 
allied genns, and the sec- 
ond belonging to the sin- 
gular and interesting ge- 
nus Phora (Fig. 123). 
The species of Antho- 
myia usually frequent 
flowers ; the larvae live in 
decaying vegetable mat- 
ter, or, like the onion 
fly, attack healthy roots ; 
while the maggots of 
Phora live in decaying 
substances. It would be 
presumptuous in the writ- 
er to attempt to describe these forms without collections of spe- 
cies from the neighborhood of the cave, for though like all the 
rest of the insects they were found three or four miles from the 
mouth, yet they may be found to occur outside of its limits, as 
the eyes and the colors of the body are as bright as in other 
species. 
Among the beetles, two species were found by Mr. Cooke. The
