荨麻是蝴蝶生存的关键。它是很多幼虫包括蛱蝶科的如花斑蛱蝶，孔雀蛱蝶等的食物来源。

Nettles are key to the survival of butterflies, as they are the primary food source for many caterpillars including those of the comma, tortoiseshell and peacock.

在厄瓜多尔，也有类似的白蛱蝶或黄蛱蝶交错杂居，但情况却与哥斯达黎加的不同。

In Ecuador, there are also white or yellow Heliconius butterflies that live close to one another and have mated freely. But that situation might be changing.

我只有一只蛱蝶和一只粉蝶。噢。

I have only a 14 tortoiseshell and a 15 brimstone.

相较于哥斯达黎加黄白两种蛱蝶“河水不犯井水”，厄瓜多尔的蛱蝶这种不同的交配倾向最终会导致进化出两种不同的物种。

The difference in mate preference could eventually lead to two distinct species, as in Costa Rica, with yellow and white butterflies that no longer interbreed.

这是只小樱蝶(蛱蝶科)——它可能今天早上才羽化的。

It's a Small Tortoiseshell - probably just hatched this morning.
