ABSTRACT Larval burrows of the Great Plains giant tiger beetle, Amblycheila cylindriformis Say, in the western short grasslands of Kansas were predominantly scattered across near vertical walls in an eroded soil canyon. The soil consisted of exposed fine-silty loam, and larval burrows were distributed on canyon walls at slopes up to 90°. The mean degree of slope for larval burrows was 55.6°. Few larval burrows were found on the more horizontal soil slopes (0–10°) near the canyon wall base, and no larval burrows were found on the nearly level, grass-covered brow of the canyon. A majority of burrows were within 1 m of another larval burrow and some were as close as 0.125 cm.
