The common parsley frog (''Pelodytes punctatus'') is a very small and slender frog with long hindlegs, flat head and vertical pupils. Males reach only 3.5, females 4.5 centimetres. The upper side of the body is variable in colour, usually with irregular green patches on a light brown, grey or light olive background. The frog's back is dotted with elongated warts, often in undulating longitudinal rows that can be orange along the flanks. Behind the protruding eyes and above the tympanum, there is short, small gland. It does not have parotid glands. The underside is white, and around the pelvis yellowy orange. In the mating season, males develop dark swellings on the insides of their digits and forelimbs, as well as on the chest. The males' forelimbs are stronger than females'. == Reproduction == In France, the breeding season lasts from the end of February to early April; in Portugal, it is from November to March. In Andalusia, this parsley frog may spawn several times a year. For laying places, it prefers weedy ponds and sometimes streams. The males create a relatively quiet croaking noise with the help of their paired inner vocal sacs, under water. The females may respond with a "kee, kee" vocalisation, similar to those of the little bustard and corn crake. During mating, the male grabs the female around the waist with its front limbs, not under the arms, as the Neobatrachia do (also see amplexus). For laying the eggs, the amplexed couple will seek a vertical twig or reed in the water, on which the female attaches an egg mass only a few centimetres long, containing 40 to 300 eggs. These are dark grey to black on top and covered in jelly. The tadpoles need approximately three months until metamorphosis if no hibernation intervenes. Previous to this, they can reach a considerable 6.5 centimetres (9.5 cm) - longer than the adult animal!
