Over the same period that the sample of scats was collected, a much smaller food sample of 73 prey items was collected by squeezing recently eaten food from the racers' stomachs, or by finding the snakes actually swallowing their prey. These items from stomachs are listed separately because they include relatively more vertebrates than do the items from scats. A grasshopper or cricket eaten by a large racer might have passed undetected, while a relatively large item such as a vole or lizard would have produced a conspicuous bulge in the snake that ate it, and would have excited the curiosity of the investigator. A second difference is that the items from stomachs included several frogs, whereas amphibians were absent from the much larger sample from scats. A third difference is that the many insects found in stomachs were all orthopterans with the exceptions of three noctuid moths and the larva of a moth. Miscellaneous insects, such as beetles, bees and ants recorded from scats were not found in stomachs. Amphibians eaten are digested so completely that no recognizable parts of them are to be found in scats, but remains of the insects previously eaten by amphibians are to be seen in racers' scats. If not recognized as secondary items, such remains might lead to erroneous conclusions regarding the racer's food. The items from stomachs were as follows: 21 grasshoppers (5 oedipines, 4 tryxalines, 5 _Melanoplus bivittatus_, 3 _M. differentialis_, 1 _M. femur-rubrum_ and one each of _Chortophaga viridifasciata_, _Dissosteira carolina_, and _Sphargemon equale_); 8 crickets (_Gryllus_ sp.), 3 katydids, 3 camel crickets (_Ceuthophilus_ sp.), 3 noctuid moths, 1 larva of a moth; 10 voles (_Microtus ochrogaster_), 6 white-footed mice (5 _Peromyscus leucopus_ and 1 _P. maniculatus_), 4 harvest mice (_Reithrodontomys megalotis_); 1 shrew (_Cryptotis parva_); 4 snakes (3 _Thamnophis sirtalis_, 1 _Storeria dekayi_); 4 lizards (2 _Eumeces obsoletus_, 1 _Cnemidophorus sexlineatus_, 1 _Ophisaurus attenuatus_); 4 frogs (_Rana pipiens_), 1 tree-frog (_Hyla versicolor_).
