STAPHYLINIDS OF CAYMAN ISLANDS—BLACKWELDER 121 
During the rest of the night the insect catch was large, but only about 
1,500 specimens of this staphylinid came in. 
“On the following evening, May 30, the quantitative method of 
counting indicated that at least 25,000 specimens of this species were 
taken between 7:30 and 9:30 r.m. During the rest of the night only 
about 2,500 specimens were taken in the trap. After a similar experi- 
ence on May 31, the trap was removed from the site, as most of the 
other insects taken were in such bad condition as a result of the hordes 
of Bledius that they were quite useless. 
“The other traps were set less than a quarter of a mile away but in 
different habitats; one was in a pasture, and the other was near the 
top of a beach. In neither of these was there taken any specimen of 
this Bledius at any time.”
