Unleashing Curiosity, Igniting Discovery - The Science Fusion

A brand new species of fluffy longhorn beetle present in Queensland, Australia

James Tweed

An entomologist tenting together with his companion in Queensland, Australia, has discovered what could also be a contender for Australia’s, and maybe the world’s, fluffiest beetle.

The invention was made by James Tweed on the College of Queensland throughout Christmas 2021 at Binna Burra Lodge in Queensland’s Gold Coast Hinterland.

As he emerged from his tent, Tweed, who usually research the bugs of Norfolk Island within the South Pacific, observed what he thought have been droppings on a standard, flax-like shrub of the genus Lomandra. However on nearer examination, he noticed it was truly a spectacular, 10-millimetre-long purple and black beetle lined in hair, which was particularly thick across the prime half of its physique.

He shortly realised it was a kind of longhorn beetle – a household with round 36,000 described species – however there was nothing corresponding to it that was recognized elsewhere. It has been designated as a brand new genus and species named Excastra albopilosa, which interprets to “from the camp, white and bushy”.

“There’s fairly a number of beetles which might be very hirsute,” says Tweed. “However this one is de facto distinctive within the size of the hairs and the patterning. It’s not unusual for a beetle to be bushy, but it surely’s unusual to be this bushy.”

Whereas it isn’t recognized why the beetle is so bushy, one potential clarification is that it makes it look as if it’s contaminated with a fungus and therefore unpalatable to predators, says Tweed.

The person he collected, which is now saved as the kind specimen within the Australian Nationwide Insect Assortment, is the one one which has been discovered regardless of quite a few searches across the campsite for the reason that discovery.

It’s prone to be a comparatively uncommon species, says Tweed. “Nonetheless, it might even be widespread however we simply haven’t discovered the place it lives but – for all we all know, it might be residing within the tops of timber the place we haven’t surveyed.”
