What to look for
A flash of electric blue at the back of a cave or ledge. Bring a torch and shine it gently into the overhangs. Blue devils are territorial and often live in the same crevice for years.
Seeing them responsibly
Blue devils are protected in NSW. Don’t reach into their cave, and keep the torch beam off their eyes for long periods.
