Cricket Frog, Fejervarya limnocharis
The Cricket Frog (Fejervarya limnocharis) is a species of frog found widely distributed within South Asia. Molecular studies of this species’ complex proposes that there may be multiple species involved.
This species is very closely related to Rana tigrina, from which it differs in smaller size, half webbed toes, slight development of the fringe on the fifth toe, and usually in the presence of a small outer metatarsal tubercle. The length and the shape of the snout, the size of the inner metatarsal tubercle, and the relative length of the hind limbs and of the fourth toe vary to an extreme degree. The tibio-tarsal articulation normally reaches the eye, or between the latter and the end of the snout, but in some specimens, it reaches considerably beyond the end of the snout, and the foot measures 2/3 the distance between the end of the snout and the vent. Greenish or olive, with darker spots; a light vertebral line or band often present; sometimes a light line along the inner side of the leg; sides of thighs black-marbled; throat of male normally with two large black blotches, occasionally connected and forming a ‘M’.
This species measures two to five inches from snout to vent.
The species creates a complex with several genetic variants that may represent multiple species.
This species, being widely distributed, can be found from China and Southern Japan, throughout India, Sri Lanka, and Burma to the Malay Peninsula and Archipelago. In the Himalayas it occurs to up to seven thousand feet. Stoliczka observed that it normally doesn’t hesitate to take to the sea or brackish water. In Pakistan, it occurs in the Indus drainage from the delta north at least to Rawalpindi.
