The wacky thing
Male peacock spiders court females by raising a flap-like extension of their abdomen — covered in iridescent blues, reds, and oranges — into a fan, then waving specially adapted third legs alongside it while vibrating their whole body in a rapid, precise dance. If the female isn't impressed at any point in the routine, she often eats him. Some species' dances have been compared by researchers to a tiny, extremely enthusiastic backup dancer.
Overview
Peacock spiders (genus Maratus) are a group of over 90 known species of tiny jumping spiders native to Australia, most just 3–5mm long. Despite their minuscule size, males have some of the most elaborate courtship displays in the animal kingdom, combining vivid coloration, complex choreographed movement, and vibrational signals sent through the ground to the watching female.
Found in
Various habitats across Australia, from coastal dunes to woodland leaf litter, depending on species.
Things worth knowing
- 1
Each of the 90+ known Maratus species has its own distinct dance choreography and color pattern — new species are still being discovered and described regularly.
- 2
The fan-like flap is an extension of the abdomen supported by hydraulic pressure, not muscle, and can only be raised into its full displayed shape when the spider is actively courting.
- 3
If a male's display fails to impress or is poorly timed, females frequently attack and eat the suitor — misjudging the dance can be fatal.
- 4
Peacock spiders also communicate through vibrations transmitted along the surface they're standing on, a signal channel largely invisible to human observers without specialized equipment.
- 5
Despite the vivid displays, peacock spiders are harmless to humans — they're too small to bite through skin and have no medically significant venom.
