Green Tiger Beetle, Allan Drewitt, Natural EnglandIt may be common, with a liking for brownfield sites as well as heathland and sandy dunes, but the Green Tiger Beetle, with its iridescent green colouring and scuttling, long-legged run, is always a delight to see. They are active throughout the summer and into the early autumn, and you can spot them either running along the ground as they hunt for prey, or basking on bare, sandy earth as they soak up the sunshine on warm days. You might see them flying on buzzing wings when they are disturbed.

Green Tiger Beetle, Erisey Barton, The Lizard, Sarah BoardThey prey on small invertebrates, using their strong mandibles. Females lay their eggs individually in separate burrows, where the larva remains as it develops, anchored by a spine on its back. The larvae also have mandibles, and are just as fierce predators as the adults. They use their burrow as a pitfall trap, quickly devouring unfortunate prey, such as ants and small spiders, that falls in.
