In North America, Leptodactylus fragilis is found from the southern tip of Texas, south through Central America to Venezuela in northern South America.
Leptodactylus fragilis is nocturnal and burrows in the damp soil during the day, foraging at night.
Breeding in Leptodactylus fragilis takes place during heavy rains in the spring. Eggs are laid in whipped foam secretions in a depression at the base of vegetation near water; tadpoles are protected within this mass, even in dry weather. Tadpoles are "freed" from nest with rains that flood the depression.
The habitat of Leptodactylus fragilis consists of various moist places including roadside ditches, irrigated fields, and low grasslands.
The Mexican white-lipped frog is not a protected species in Texas and can be legally collected with a hunting license.
In Texas, Leptodactylus fragilis is restricted to the extreme southern tip of the state in Cameron, Hidalgo and Starr Counties.
