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!
Common parsley frogs are found in open or semi-open, even arid landscapes, that are typically characterised by the occurrence of Pine and Holm oak stands. They seem to furthermore prefer calcareous soils. In the North of its distribution, this parsley frog hibernates from November to February/March, but does not hibernate in the South.
The distribution ranges from Spain up to the North of France, including France, Spain, Portugal and a small part of Northwestern Italy (Piemont and Liguria). In altitude, these frogs reach from sea level to middle mountainous regions. The distribution in France is the most continuous; here, only the Eastern edge and parts of the South West are not colonised. In the South of the Iberian peninsula, the Iberian parsley frog (P. ibericus Sánchez-Herraíz, Barbadillo-Escrivá, Machordom & Sanchíz, 2000) has come to be regarded as a separate species in recent years. The third Pelodytes species, the Caucasian parsley frog (P. caucasicus Boulenger, 1896), is spatially set apart with its distribution in the Caucasus and Turkey. This may be an example of allopatric speciation in ice age refugia.
In the UK this pest has found its self in local ponds, competing with local wildlife. There however has been no record of breeding and most have been terminated from the wilderness of the UK. There is no evidence supporting how they got here, they were most likely released by pet owners.
Ecology and behaviourEdit
During the day, the animals rest under stones or in burrows that they dig. They can also climb reasonably well. They hunt insects at night, and are predated by barn owls, amongst others.
