Description

The green tiger beetle is a small beetle of the ground beetle family, 12-15 millimetres long, with splendid colours. Its body is a bright metallic green, with a few pale rounded spots on the wing cases and legs with coppery sheen. It has large protruding eyes, long runner's legs and powerful curved jaws, among the most effective hunting tools in the insect world.

Habitat and distribution

It is widespread across Eurasia. It favours open, dry, sunny habitats: dirt paths, sandy clearings, heaths, slopes and bare ground, where it basks in the sun and hunts.

Behaviour

It is an extraordinarily fast diurnal predator: it runs in bursts over the ground chasing prey and, if disturbed, takes short flights to escape before resuming the hunt. With its large jaws it catches ants, spiders and other small invertebrates. The larva is also carnivorous: it lives in a vertical burrow dug into the ground, lying in wait, and seizes passing prey with a lightning strike.

Did you know?

The tiger beetle is among the fastest insects in the world relative to its size: it runs so fast that, it is said, it becomes momentarily 'blind', having to stop to refocus on its prey. Its common name alludes to its nature as a fierce hunter.

Notes

It is a useful and fascinating insect, an indicator of open, well-preserved habitats. It is not dangerous to humans, though its large jaws can give a nip if handled.

Pros

  • Splendid metallic-green colour
  • Lightning-fast hunter, useful predator
  • Indicator of open, well-preserved habitats

Cons

  • Depends on bare, sunny ground
  • Large jaws can nip if handled
  • Sensitive to the closing over of open habitats

FAQ

Why is it called a tiger beetle?
The name alludes to its nature as a fierce, lightning-fast hunter. With its large jaws and dashing run, it chases and catches prey like a small predator, a miniature tiger.
Is it really that fast?
Yes, it is among the fastest insects in the world relative to its size. It runs so fast that it has to stop for an instant to refocus on its prey, as its vision cannot keep pace with the run.
How does the larva hunt?
The larva lives in a vertical burrow dug into the ground, with its head level with the surface. It lies in wait and, when prey comes within reach, strikes in a flash, seizing it with its jaws.
Is it dangerous to humans?
No, it is completely harmless. Its large jaws serve to catch prey and, if handled, can at most give a slight nip, with no consequences.
