It can take up to 2 to 3 years before frogs breed - I built my pond in and I had 30 frogs breeding in last year I had over 46 this year around the same number. So keep an eye on your pond - especially at night with a torch when most things are out and you may find a surprise visit from frogs later in the year.
New Posts. Members Profile. Post Reply. I have just made a very small pond in my garden and would like to introduce some frogs to it. What time of year are frogs spawning? Can i just scoop them out of a public pond and take them home?
Ponds that are shady and have lots of reeds and other vegetation around them are particularly popular with breeding frogs. But frogs will even lay their spawn in temporary puddles. When you do find frogspawn, as with all wildlife, it's better to enjoy it from a distance and not disturb it.
You shouldn't move frogspawn from one pond to another, because conditions in the new pond may not be suitable and it can also spread diseases deadly to amphibians.
Frogspawn of the common frog Rana temporaria. The black dots are the eggs surrounded by a jelly-like casing. Frogspawn eggs bunch together in large clumps. This is how to tell the difference between frogspawn and toadspawn, which instead forms thin ribbons on underwater plants. It takes around three weeks for young tadpoles to emerge. These tailed juveniles can be found swimming in ponds from around March. Tadpoles are fully aquatic and have gills that they use to breathe underwater as they forage and feed.
In younger tadpoles the gills are external and visible with a microscope or magnifying glass. Young tadpoles begin by eating things like algae. As they grow, they go on to munch leaves, moss and sometimes even small insects. Common frog tadpoles develop distinctive colouring which can help you identify them. They change from darker colours to a mottled golden brown as they age, distinguishing them from the black common toad tadpoles found in similar habitats.
As the months pass into April and May, you should be able to spot dramatic changes at the edges of your local pond as tadpoles slowly change into frogs. This process is called metamorphosis. After about 16 weeks from when tadpoles hatch, the legs begin to form, followed by the arms. The tails gradually are absorbed into the body. Alongside this process, lungs form to allow the young frog to breathe above water. A pond's particular environment can have a big impact on the speed at which tadpoles transform.
For example, if there is a lot of food or the temperature is cold, tadpoles can delay the process of metamorphosis by several months. They can also increase the rate of change if this benefits them, for instance if they are sharing the pond with hungry predators such as fish. Once their new bodies are developed, froglets leave the pond and begin a new semi-aquatic phase of their lives, splitting their time between land and water like all amphibians.
A young common frog sitting by the side of a pool. Baby frogs are commonly called froglets, and scientists often call them metamorphs. Their diet also changes, with the young frogs now feeding on a range of invertebrates including flies, slugs and snails.
They still have a lot of growing to do. Common frogs reach up to 13 centimetres in length as adults males are smaller than females and live for around five to 10 years. Many animals eat frogspawn and tadpoles in the UK, including fish, beetles, newts, dragonfly larvae, rats and even foxes and hedgehogs. Froglets and adult frogs are eaten by snakes, owls and other birds of prey, as well as mammals such as otters, badgers and weasels.
Unsuitable temperatures can also be a big risk to the development of frogspawn, which needs light and warmth. Spring frosts can be particularly bad news, as frogspawn will die if the temperature drops too low.
But some of the largest threats to frogs in the UK come from human activities. Find out about these threats and how you can help. Although frogspawn might be the most obvious inhabitant of your local pond in spring, there's plenty more to life beneath the surface.
