Tadpole clusters in pond, Netherlands
This is a pond close to where I live, which I visit frequently during the summer for macro photography. Each year, around the end of may, beginning of june, the shores of the pond are flooded with tiny frogs, so small that you may mistake them as insects and unknowingly step on them. On this photo, we can see that this year's summer will likely see a new invasion.

"Rana temporaria" is found throughout much of Europe as far north as well north of the Arctic Circle in Scandinavia and as far east as the Urals, except for most of Iberia, southern Italy, and the southern Balkans. The farthest west it can be found is Ireland, where it has long been thought erroneously to be an entirely introduced species.
