Hawaii is a beautiful tropical paradise and home to terrifying, eerie rawly predators. There is Spiders blocking their prey in the air And it poisons It can extend nearly 15 inches long.

And there is the evolutionary rarity of carnivorous caterpillars. And now, scientists have discovered not only a food for other insects, but also a very hungry caterpillar.

Called The Bone Collector, this scary taste in Caterpillar and Couture was explained in the Journal on Thursday Science. “The behavior was completely unknown,” said Daniel Rubinoff, an entomologist and research author at the University of Hawaii at Manoa. His team initially compared caterpillars to raw crime scenes.

Bone collector’s caterpillar is found only within the six-square miles of a single mountain range on Oahu. So it only exists in co-necks spun by spiders in logs and rock caves. When caterpillars almost slip about the web, they clean dead insects and other arthropods that have been soaked in sticky silk.

According to David Wagner, an entomologist at the University of Connecticut, Caterpillar’s reliance on Spiders presents one of nature’s most unlikely connections, as he was not involved in new research. “It’s amazing how caterpillars tie their fate to spiders. It’s clear and current danger for both caterpillars and moth,” Dr. Wagner said. He only knows one other species that frequently visits spider nets. But the species are vegetarians who snack on plant ingredients caught in the web.

Dr. Rubinoff first encountered the bone collector’s caterpillar in 2008 while examining the inner web of a hollow tree. Caterpillars are extremely rare. Over 150 field studies in the area produced only 62 bone collector specimens.

Scientists determined that bone collectors belong to hyposporoma, a diverse genus of small moth species found only in Hawaii. The larva stage rotates silk protective cases that resemble everything from Kandi wrappers to cigars.

Like hermit crabs, these caterpillars carry their cases before moving before appearing as fully grown moth. Some species decorate mobile homes with wood, algae and shells to blend into the environment.

Bone collector Caterpillar gives an eerie spin on his practice. Using silk, caterpillars weave small pieces of dead insects they encounter on the spider web. Researchers have identified parts from six families of insects attached to caterpillars, including the heads of weevils and the abdomen of beetles. Caterpillar also incorporates fragments of the exoskeleton molted by Arachnid’s neighbors.

Dr. Rubinoff and his colleagues brought some bone collectors back to the lab. They were surprised at how loud the caterpillars were when they were to decorate their lawsuit. “These caterpillars can identify differences in the objects of their environment,” Dr. Rubinov said. The larvae chose to avoid other available debris and harvest only from insect corpses.

But the ruins are not. Caterpillar uses the lower jaw to carefully rotate and investigate future body parts. Something too large will bite you in a more comfortable size.

The caterpillars gathering bones are too noisy about their diet. The team discovered that caterpillars, including one another, eat insect prey that can catch.

But they have to fight against an eight-legged landowner. The team observed bone collector caterpillars that frequently and frequently visit the web of at least four introduced spider species. The team assumes that Caterpillar’s horrifying outfits will help disguise them among insects trapped in the web. Dr. Wagner suspects caterpillars will undermine the appeal of their culinary culinary by disguising them as “a pile of garbage” of objects that the spiders didn’t scarf down.

The bone collector approach appears to be working. Researchers never observed spiders consuming bone collectors or engulfing them in silk.

The team studied bone collector genetics and determined that it was likely that it diverged from other carnivorous hypofluvium caterpillars more than 5 million years ago. This may be millions of years before Oahu emerged from beneath the sea, and the ancestors of bone collectors once lived on other islands.

Bone collector’s current paradise slices may be at risk. Caterpillars have adapted to thrive in nets spun by non-native spider species, but their habitat is threatened by invasive ants and parasitic wasps. According to Dr. Rubinoff, conservation attention is desperately needed to save endemic arthropods in Hawaii.
