Moths seem to be made for Halloween. They’re largely nocturnal, often outlandish in appearance and bear creepy names such as Lunar Thorn, Cloaked Carpet, Bordered Gothic and (best of all) Puss Moth. The webs of the ermine moth caterpillar cover trees like ghostly shrouds, while the hairy caterpillars of the oak processionary moth release rash-inducing toxins. Spookiest of all is the Death’s-head Hawk-moth, which bears a skull-like mark on its thorax and can squeak like a mouse.
