Chiricahua Leopard Frog vs. Lowland Leopard Frog

Both live in central and southeastern Arizona: the Chiricahua mostly at springs and stock tanks in oak and pine country, the Lowland in desert streams below the Mogollon Rim; they meet where the two belts touch. Both have back ridges that break up and turn inward near the hips. A: Rough, with many small raised bumps in the Chiricahua Leopard Frog; smoother in the Lowland Leopard Frog. B: Set high on the head and turned upward in the Chiricahua Leopard Frog; set normally on the side of the head in the Lowland Leopard Frog. C: Salt-and-pepper: fine pale dots on dark in the Chiricahua Leopard Frog; a tight, dark-brown net in the Lowland Leopard Frog. D: Pale, no yellow wash in the Chiricahua Leopard Frog; often washed yellowish in the Lowland Leopard Frog. E: Larger and stockier: to 4.3 in (11 cm) in the Chiricahua Leopard Frog; smaller: to 3.4 in (8.6 cm) in the Lowland Leopard Frog. Calls differ: a low snore of 1 to 2 seconds (Chiricahua) vs a quiet run of short low notes over 3 to 8 seconds (Lowland).
