If you have a fear of creepy crawlies, you may want to approach with caution.

A YouTube user has captured a mantidfly, which looks like a wasp but has the front legs, sharp jaws and bulging eyes of a praying mantis, tucking into a small fly.

The video shows the active hunter feasting on the fly's body, which it holds in its front legs and nibbles on like a human stripping a cob of corn or a pork rib.

Utah resident Ed Kern kept the insect captive for four days so he could film it, even nicknaming the strange-looking fly Tyler Durden, after a character from Fight Club.

‘Tyler is not afraid of anything, you can pick him up and he doesn't even react,’ Mr Kern said.

‘I fed him about a half dozen flies before I let him go.

‘I only saw him fly once, and that is when he flew away, never to be seen again.’

While the exact species of mantidfly in the video is not clear, it is one of many to mimic a wasp, presumably to disguise its fearsome front legs and superior hunting method.

MANTIDFLIES VS SPIDERS The larvae of some mantidflies feed on the egg sacs of spiders. They find and 'board' spiders then enter the egg sac while it’s under construction. One inside, they pierce and drain eggs with their modified mandibles. It’s not known whether they have a way of seeking out spiders from a distance, or whether it is a matter of luck, because female spiders regularly produce egg clutches containing up to a thousands eggs. They also feed on spider ‘blood’ while aboard adult spiders. Advertisement

It has patterns on its four wings and a stripy body to appear like a wasp, although looks considerably larger.

Mantidflies grow to 1.9 inches (5cm) long and tend to be nocturnal.

In the video, the insect can be seen pulling itself along Mr Kern’s finger with its raptorial front legs, which have distinctive protruding tibial spines like a praying mantis.

The praying mantis gets its name because it holds its front legs aloft as if folded in prayer, waiting to catch a fly that lands in front of it, for example.

The mantidfly can be seen adopting a similar pose in the video and can also grab hapless smaller insects at lightning speed and grasp them in its distinctive forearms.

The footage also reveals how the scary-looking animal devours a fly - first by pulling off its legs, then manipulating it in its mantis-like front legs, so it can nibble along the fly’s body with ease.

Mantidflies, from the Mantispidae family, feed on smaller insects.

They have a pair of sharp mandibles, like the famous praying mantis, that are used for biting, cutting and holding food.

They also have the mantis’ compound bulging eyes that work together to give it a keen sense of vision.

While the creature may look as though it escaped from a sci-fi film, there are actually 400 types of mantidflies, which are relatively common in North America and in the tropics.

There are five species living in Europe.
