However, the spider world is far more diverse, and perhaps far cuter, than you might think. 

Peacock spiders, known for their elaborate mating dances and fantastically-colored abdomens, are one such species. Roughly the size of a fingernail, peacock spiders are strikingly adorable. 

Joseph Schubert, an entomologist with the Museums Victoria in Australia, discovered seven new species of these spiders. Did you know that Schubert originally feared these colorful spiders? Yet, at just 22 years of age, he's helped discover 12 new species in total!

The newly discovered spiders bring the number of known species to 86 known species in the world. These spiders exhibit unique patterns, ranging from Vincent Van Gogh’s famous Starry Night painting to a brilliant orange-striped ocean. 

Why Are They Called “Peacock” Spiders?

Peacock spiders are tiny jumping spiders that range in size from two to six millimeters. While female peacock spiders come in plain shades of mottled brown or beige, male spiders are much more exotic. 

Male spiders are equipped with glittering scales and lateral abdominal flaps that they use to woo females in complex mating dances. In these dances, the males scuttle about, raising their abdomens up and down, waving their third legs, and extending their lateral flaps. Besides demonstrating showy colors and movements, the males’ abdominal movements also generate simple vibrations.

All of this is similar to how male peacocks perform when recruiting a mate, giving these unique spiders their name. 

Where Do Peacock Spiders Live?

The spiders are generally most active around breeding season with mature males emerging from August to December when it is spring in the southern hemisphere. Mature females emerge a little later, though they also retreat in December to lay and guard their egg sacs. 

What Do Peacock Spiders Eat?

Peacock spiders make use of their keen eyesight, superior color vision, and venomous fangs to prey on various insects, as well as other spiders—sneaking up behind unknowing victims and pouncing upon them.

Before you get worried, peacock spider fangs are so tiny they are practically harmless to humans. 

Peacock spiders are captivating creatures, and as Schubert himself says, “there are more out there to be found.” Could you be the next to discover a new species of peacock spiders?
