69 could live into their third year and females might live one year longer. The same data showed that males might grow to 38 mm carapace length (CL) while females might reach 47 mm CL. These were maximum lengths as the vast majority didn't live past their second year and 20-25 mm CL. 180 FEEDING AND SPECIES INTERACTIONS There is nothing in the literature on the feeding habits of this species. We are left with making some inferences (guesses) based on what we do know about them. First off, they are terrestrial, building burrows in grasslands, wet meadows and mesic (moist) forests. We also know that they come out of their burrows in the early evening. Therefore, they must be foraging for food at this time. It is possible that they could be clipping and eating vegetation. It is also possible that they are catching and eating insects or earthworms. This is another one of those questions that may remain unanswered. DISTRIBUTION The range of the Prairie crayfish fits within the central portion of the eastern tallgrass prairie. It runs from southeastern Wisconsin through Illinois, Iowa and Missouri to southeast Nebraska, eastern Kansas and Oklahoma and into northeastern Texas. 230 In Nebraska, they are found only in the southeastern corner of the state. To date, I have found them five times, three in southwest Lancaster and northwest Gage Counties and twice in Pawnee County. They are probably more common in the southeastern corner of the state than these collections indicate.
