Conservation Status:

State: None

Federal: None
NatureServe State: SNA - Not Applicable
NatureServe National: N5 - Secure
NatureServe Global: G5 - Secure
CITES: None
Diagnosis:
A large ans slender treefrog that ranges in length from 32-64 mm (1.25-2.5 in). It has smooth skin and long legs. Dorsally it is usually bright green, but may vary infrequently from yellow to slate-gray. There are often a few small yellow spots on the dorsum. The venter is white and unmarked. There is usually a dark-bordered white to yellow stripe along each side of varying length.

Distribution:
Known only from isolated introductions from fish (Douglas County), potted plants (Wichita), and flower (Ellis County) shipments. This species does not establish viable populations in Kansas, however the Douglas County introduction persisted for several years (J. T. Collins, pers. comm.).

Douglas (38); Ellis (3); Sedgwick (1); Trego (3);

Fossil History:
Not known from Kansas.

Natural History:
The male breeding call is described as a nasal, bell-like "quonk" repeated up to 75 times a minute.

Occurrence Activity:
Number of Unique Obervations (=days): 4; Range: 26 May to 17 Oct
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.
Number of Unique Obervations: ; Range: ; Interquartile range: ;

Remarks:
This species infrequently turns up in Kansas from plant shipment that originate further south and east. There are natural populations within 50 miles of the Kansas border along the Verdigris River in Oklahoma. A recent introduction and large chorusing/breeding population (UMC 1841P) was reported from just north of Joplin, Missouri (8.5 miles [13.7 km] east of the Cherokee County, Kansas border) (Daniel et al., 2011). This population (discovered in 2010) is three miles from the Spring River, which flows into Kansas east of Crestline.
