Western Narrow-Mouthed Toad

Family: 
Microhylidae (narrow-mouthed toads) in the order Anura (frogs)
Description: 

Like the eastern narrow-mouthed toad, this species has a plump body, small pointed head and a fold of skin behind the eyes. This species is typically uniform in color from tan to gray or olive green, with few markings. The belly is white.  Makes a high-pitched short "peel" sound that sounds similar to the buzz of a bee.

Size: 
Head-body length: 7/8 to 1 1/2 inches.
Habitat and conservation: 
Found mainly in grasslands but also along rocky wooded hills and edges of marshes.
Foods: 
Mostly ants. This species has evolved a toxic skin secretion that may protect it from ant bites, since it is known to sit on anthills while eating its preferred food.
Distribution in Missouri: 
Western Missouri and along the Missouri River floodplain.
Status: 
Common where present. This species used to be called the Great Plains narrow-mouthed toad.
Life cycle: 
Breeds during warm, heavy rains in summer in temporary pools, flooded fields and ditches. This species and its close relative, the eastern narrow-mouthed toad, often occur in the same areas, but their mating calls are so different they don't interbreed and hybridize.
