The Agile Frog lives throughout most of Europe besides the northern regions.

The breeding season starts shortly after the frogs awake from their hibernation (between February and March) and lasts until April. Males gather in large groups in the shallows of water bodies to call. Once the female arrives, the males try to grasp the female behind in the amplexus position. The female frog lays between 450 – 1800 eggs. The tadpoles usually take 2 to 4 months to complete their metamorphosis but have been known stay as tadpoles over winter and complete it in spring.

The International Union for the Conservation of Nature (IUCN) Red List assesses the Agile Frog as Least Concern for Extinction. The frog has a wide range and are numerous throughout it. Though in some areas of its range, it has been harder to find due to draining of wetlands and cutting down woodlands they call home. On the isle of Jersey, the frogs are considered critically endangered and they have even re-introduced the species there.
