Agreeable Tiger Moth

Fascinating facts about the Agreeable Tiger Moth

• A tiger moth caterpillar covered in hair-like setae can absorb toxins from poisonous plants without dying — then wears those poisons in its own skin as armour. Birds learn fast: one peck at a spiny, toxic caterpillar and they avoid tiger moths for life. The moth's bold orange and black wings are a warning label that took millions of years to perfect, yet costs nothing to display.
• When a bat's sonar hits a tiger moth's wing, the moth doesn't flee — it jams the signal. Tiny scales on its wings scatter the bat's echolocation clicks, creating acoustic camouflage. Some species go further, generating their own ultrasonic clicks to confuse the predator's brain. An evolutionary arms race written in sound waves, invisible to human ears.
• The agreeable tiger moth caterpillar spins silk not just for a cocoon but as a survival tool. It wraps itself in a silken sleeping bag to shed its skin, shedding up to five times before pupation. Each moult exposes fresh, unstained warning colours — a refreshed advertisement of toxicity that costs the caterpillar almost nothing but gains it safer passage through a predator-filled world.
• Tiger moth caterpillars are the only known insects to produce their own ultrasonic calls — clicks and chirps that mimic bat echolocation so perfectly that bats hesitate mid-strike. A caterpillar no bigger than a fingernail weaponises sound, hijacking the bat's own language to buy itself seconds of survival. This trick didn't exist 50 million years ago; it evolved in real time.
• Adult agreeable tiger moths live only 2–3 weeks but pack those days with frenzy. Males patrol at dusk hunting by pheromone, following a female's scent plume from 100 metres away through darkness. They mate once, lay eggs once, then die. No time for learning, no second chances — just instinct, reproduction, and the end. Their whole life is an advertisement: I found a mate and passed on my toxins.
