An entomologist who discovered a species of moth is auctioning the right to give it an official name, on eBay.
Eric H Metzler found the moth in New Mexico eight years ago, but it has only recently been acknowledged as a new species.
Bidding currently stands at $7,100 (£4,581), with three days left on the auction.
The winner's chosen name will have to be Latinised, and go through an approval process.
The money raised from the auction will go to the Western National Parks Association, which funded Mr Metzler's research.
