Three new disco-dancing peacock spider species have been discovered in Western Australia.
The males of these previously unknown species are flamboyant* showmen. Though they’re only as large as a grain of rice, the males have the bright colours of peacocks and do an elaborate funky disco dance to attract female mates.
They were found by citizen scientists, a dedicated group of volunteers that drives thousands of kilometres around Australia trying to find these beautiful creatures.
Scientist Joseph Schubert identified them after they were collected at Lake Jasper and Mount Romance in Australia’s southwest.
He posted an image on social media platform Twitter announcing the spiders had been officially named.
“Meet Australia’s three newest species,” Mr Schubert wrote. “As of today they are officially named: Maratus aquilus, Maratus felinus, and Maratus combustus.”

Mr Schubert, who helped discover the spiders while volunteering with Project Maratus, said the spiders were distinctive with brightly coloured markings. He explained on Twitter that he had given some of his spiders their names to correlate* with patterns on their abdomens.

Mr Schubert said 73 of the Maratus — peacock — spider species have now been named.
The male spiders are brightly coloured, while the females are drab* and difficult to identify. The spiders are of interest for their elaborate courtship behaviour, which includes the males doing a dance to impress the females.

“They’re incredibly small but so charismatic and so colourful,” Mr Schubert told news site 10 Daily.
He said peacock spiders were unique from other spiders, by being identifiable by their colourful markings on their abdomen. Other spiders are identified by their fangs, or spider hair.

Mr Schubert said the area where they were found, at Lake Jasper and Mount Romance in Western Australia was a “biodiversity* hotspot”, meaning there was an important number and range of animal and plant species there.
Mr Schubert is a biologist at Monash University, Victoria, whose paid job is researching a group of invertebrates* known as Collembola, which are six-legged relatives of insects.
He told Forbes magazine in an interview that he was once an arachnophobe*, but that peacock spiders aren’t at all scary.
“They’re a great group to expose arachnophobes to, as they’re quite cute compared to the scary, hairy spiders we’re used to seeing.”

1. Puppet Show
Work in groups of three to write and create a small puppet show to perform to some younger students in your school. You should write the script to incorporate the information about the peacock spider contained in the Kids News article.
Create puppets by drawing or printing images of the new peacock spider species and sticking them to a craft/icy-pole sticks.
Perform your puppet show to a younger class at a time to suit both classes.
