County Breakdown: County Name (# occurrences):
Jewell (2);

Fossil History:
A few limb bones, vertebrae and ilia are known from the Pleistocene Cudahy fauna of Meade County, Kansas, probably of Kansan glacial age (Hibbard, 1958). Specimens (KUMVP uncatalogued and UMMVP 39338) have been recovered from both the Sunibrite and the Cudahy pits (Tihen, 1962).
Fossils from the Courtland Canal and Hall Ash local faunas of Jewell County (Rogers, 1982; Eshelman and Hager, 1984) are referable to this taxon.

Natural History:
Not currently known to exist in Kansas.

Number of Unique Obervations (=days): 0; Range: 01 Jan to 01 Jan
Chorusing:

Audio recording by Keith Coleman.

Chorusing Phenology: The black outlined dots denote the Julian date (day of the year; 1 January = 1 to 31 December = 365) an observation was made. The thin red line depicts the range of dates between the beginning of the first, and end of the fourth quartile (excluding outliers; Tukey method). The thick light blue bar represents the second and third quartile (interquartile range; the middle 50% of all observations). Only one observation per Julian date is included in the graphs; so a date with multiple observations carries the same weight as a date with only one observation. The vertical bars correspond to the 12 months of the year; January through December.
