"When cave crickets go out for dinner, they really go, researchers say"

(...)Reporting in the journal American Midland Naturalist, a team of researchers led by Steven J. Taylor, an entomologist with the Illinois Natural History Survey and University of Illinois at Urbana-Champaign, reported that the crickets, Ceuthophilus secretus, journey at night in high numbers up to 80 meters from the entrances of central Texas caves. A few crickets traveled up to 105 meters to feed.
Previous research indicated that most crickets stay within 50 meters from their caves. As part of the formula for a buffer zone proposed by the U.S. Fish and Wildlife Service, a range for cricket foraging was recommended. The buffer zone also extends outward to control for the effects of invasive red imported fire ants (Solenopsis invicta Buren). The buffer-zone formula helps to guide where to apply treatment applications against the ants. (...)
