Pelophylax kl. esculentus
● Common · protected in France
On a warm evening in May the same concert breaks out at every pond: a cacophony of croaking, rattling edible frogs. This is the frog of French cuisses de grenouilles. And yet the frogs’ legs on your plate almost never come from a French pond.

Where can you find them?
Difficulty: ●●●●● Very easy
On a sunny day you will see them sitting on water-lily leaves and banks. Get too close and they leap into the water with a splash.
| France | Ponds across almost the whole country, from the Dombes and the Brenne to the Camargue |
| Also | Common throughout the Netherlands and Belgium |
| Tip | Go to a pond on a warm evening in May or June and listen |
Did you know a frog uses its eyes to help it swallow? As it swallows, it pulls its eyes inwards so they push the prey towards the throat.

Behaviour & seasons
The edible frog is a true water frog: it rarely strays far from the bank. It likes to sit in the sun and wait for an insect to pass. In May and June the males croak in chorus to attract females, with their vocal sacs puffed out. Each female then lays thousands of eggs in clumps among the water plants. In autumn the frogs crawl into the mud or under leaves to hibernate.
| November – February | Hibernation in the mud or on land |
| March – April | Waking up and returning to the water |
| May – June | Croaking choruses and egg-laying |
| July – September | Tadpoles turn into young froglets |
When is the best time to see them?

From pond to plate?
Since 2007 all amphibians in France have been legally protected, and wild frogs from French ponds may not be sold. Yet France is Europe’s biggest importer of frogs’ legs: around 3,000 tonnes a year, about 80 percent from Indonesia, and most of the rest from Vietnam and Turkey. Much of that is caught in the wild, and conservation groups are worried about the impact on frogs in those countries.
If you do want to eat frogs’ legs, ask where they come from and preferably choose farmed frogs with a clear origin.

Frogs’ legs are so French that the British have long teasingly called the French ‘frogs’. The meat is tender and white, reminiscent of chicken or fish. In the Dombes, the pond country north of Lyon, and in the Vosges, they are a traditional item on the menu. The spa town of Vittel even holds a big frog festival every spring, with frogs’ legs in every shape and form.

Almost never. France imports around 3,000 tonnes a year, mainly from Indonesia. Wild French frogs may not be sold.
When can you hear frogs croaking?
Mainly on warm evenings in May and June, in the breeding season. But also on sunny days in summer.
Is the edible frog a separate species?
Not quite. It is a hybrid of the pool frog and the marsh frog that has maintained itself in the wild for a very long time.
