Streetlights trap pill bugs in "death spirals" – a new effect of light pollution

Researchers have discovered that artificial streetlights can trap thousands of woodlice (pill bugs) in circular "death spirals" — a behaviour never previously observed in the wild. The finding suggests that light pollution is unintentionally disrupting the behaviour of even the smallest ground-dwelling creatures. It is the first documented case of this type of behavioural disruption in the species.
