Fascinating facts about the Garden Tiger

• When a garden tiger moth is cornered by a predator, it floods its ears with ultrasonic clicks at 200 kilohertz — a sound so high-pitched it jams the echolocation of hunting bats mid-strike. Scientists call this acoustic jamming, and it buys the moth milliseconds to escape. The moth's own ears are tuned to detect these frequencies, a biological arms race written into sound waves.
• The caterpillar of a garden tiger is a walking pharmacy. It feeds on plants containing toxic alkaloids and pyrrolizidines, storing the poisons in its own tissue without being harmed. When it metamorphoses, those toxins move into the adult moth's body and wings, creating a 40-millimetre warning sign: bold red underwings and cream-and-black marbling that says 'I am poisonous' to any bird that learns the pattern once.
• The garden tiger moth's scientific name, Arctia caja, means 'bear-like treasure' — a name earned when specimens arrived in Europe from Russia in the 1700s so striking that collectors treated them like precious objects. Two centuries later, populations across Britain and northern Europe have crashed by 90 percent in just 50 years, with some regions losing them entirely. We named them like jewels and watched them disappear.
• Adult garden tiger moths don't feed the way you'd expect. They sip nectar from flowers and tree sap, but their digestive system is so simplified they barely extract energy from food — instead they burn through reserves built during their caterpillar phase. This is why they live only 4 to 6 weeks as adults. Everything they are, they were born with.
• The caterpillar's dense coat of bristling black and orange hairs isn't for warmth — it's a chemical delivery system. Each hair sits in a poison gland that oozes with alkaloid defences, making the caterpillar taste foul to anything trying to eat it. A bird that pecks one learns instantly and avoids all spiky caterpillars forever, a lesson written in a single bitter taste.
