Garden Carpet

Fascinating facts about the Garden Carpet

• In the 1950s, the Garden Carpet moths near Manchester turned from speckled grey to jet black — a shift visible within just 20 years. Soot from coal plants darkened tree bark, and moths with darker wings survived longer because predators couldn't see them as easily. When the air cleaned up decades later, the pale forms returned. This is one of nature's clearest real-time examples of evolution happening on a human timescale.
• A Garden Carpet caterpillar can strip a plant bare, but it leaves behind an invisible chemical signature — a plant hormone it was eating from. Other caterpillars of the same species taste that signal and scatter to find untouched plants nearby. They're communicating through chemistry, via the plant itself, without ever meeting.
• The moth's name comes from its larva's favourite meal: the leaves of bedstraw, a sprawling plant with tiny hooked hairs. The caterpillar's gut has special enzymes to break down these leaves that most insects cannot digest. From Japan to Ireland, wherever bedstraw grows, you'll find Garden Carpet moths.
• Garden Carpet moths have travelled further than most people realise. Found across the entire Palearctic — from western Ireland to eastern Japan, a span of roughly 14,000 kilometres — they're one of the widest-ranging moth species on Earth. The same species flies over moorland in Scotland and feeds on plants in the foothills of the Himalayas.
• The caterpillars use their own poo as camouflage. They gather their droppings in neat piles along the leaf edges where they feed, then position themselves beside these faecal pellets. To a bird hunting for movement and shape, the caterpillar blends seamlessly with its own waste — a form of disguise so effective it asks: what prey wouldn't use if it worked?
