A newly discovered species of beetle has been named after young climate activist Greta Thunberg.
Nelloptodes gretae bears little resemblance to its namesake - it is less than 1mm long, and has no wings or eyes.
The insect does, however, have two long pigtail-like antennae.
Scientist Dr Michael Darby said he chose the name because he was "immensely impressed" by the Swedish teenager's environmental campaigning.
N. gretae was first found in Kenya in the 1960s by William Block, who donated his samples to the Natural History Museum in London in 1978. It has been held in one of the museum's collections since.
Dr Darby was studying this collection when he came across the then-nameless species.
By naming the beetle after Ms Thunberg, he said, he "wanted to acknowledge her outstanding contribution in raising awareness of environmental issues".
It has now been formally named in the Entomologist's Monthly Magazine.
Dr Max Barclay, the museum's senior curator in charge of beetles, said the name was apt because "it is likely that undiscovered species are being lost all the time, before scientists have even named them, because of biodiversity loss".
"So it is appropriate to name one of the newest discoveries after someone who has worked so hard to champion the natural world and protect vulnerable species," he added.
