BREEDING HABITS OF CEUTHOPHILUS LATE NS,* THE 
CAMEL CRICKET 
By Clarence L. Turner 
I. INTRODUCTION 
The breeding habits of Ceuthophilus latens have not been de- 
scribed probably because it is nocturnal and hence little observed. 
During the month of October, 1914, a number were observed 
breeding in the woods on the University of Wisconsin campus. 
They did not occur in abundance and it was not possible to 
observe their breeding activities extensively in their native habi- 
tat, so they were taken to the laboratory and confined in a cage 
where the natural conditions were simulated as closely as possible. 
Some thirty individuals were taken and these furnished the data 
for this paper. 
II. HABITS AND BEHAVIOR 
Ceuthophilus is usually described as living under flat stones 
and logs in dry open woods. One species, C. stygias, lives in the 
caves of Indiana “Far back beyond the reach of any rays of 
light” according to Blatchley. 
Boards, pieces of card-board and flat stones were found to 
furnish hiding places for C. latens and convenient traps were made 
by placing such objects on clean earth in the woods and par- 
tially covering them with leaves. 
Except when disturbed C. latens shows little activity during 
the day and even at night it cannot be called active in com- 
parison to crickets, katydids and other nocturnal Orthoptera. 
In the writer’s observations most of the time during the day was 
spent resting under the debris at the bottom of the cage. At 
* The species of the specimens used in this work was kindly determined by Dr. E. M. Walker 
of Toronto University and Dr. Albert P. Morse of Wellesley College. The writer is also indebted 
to Dr. A. S. Pearse and to Dr. Wm. S. Marshall of the University of Wisconsin for references 
to literature, for a critical reading of the paper, and for suggestions.
