Is a peacock spider rare?

Peacock spiders are a group of colorful jumping spiders found mainly in Australia. With their iridescent abdominal flaps and courtship dances, peacock spiders have captured the fascination of many arachnophiles and nature enthusiasts around the world. But just how rare are these charismatic critters? Let’s take a closer look at the distribution and population status of peacock spiders to determine if they qualify as rare.

How Many Peacock Spider Species Exist?

Currently, there are around 70 described species of peacock spiders, all belonging to the genus Maratus. New species continue to be discovered each year, particularly in Australia. Just in 2022, researchers described 10 new peacock spider species found in Western Australia.

The number of peacock spider species indicates they are a relatively diverse group within the jumping spider family (Salticidae). There are over 6,000 described jumping spider species globally. So while peacock spiders make up only a small fraction (about 1%) of all jumping spiders, their diversity is on par with some entire jumping spider genera.

Where Are Peacock Spiders Found?

The vast majority of peacock spider species occur in Australia. A few species have been found on neighboring lands, including New Guinea, Tasmania, and the Solomon Islands. Within Australia, peacock spiders inhabit all states and mainland territories.

Region Number of Peacock Spider Species
Western Australia 25
New South Wales 14
Queensland 9
South Australia 7
Victoria 6
Northern Territory 5
Tasmania 3
Australian Capital Territory 1

As the table shows, Western Australia harbors the most peacock spider diversity, housing over one-third of all known species. New South Wales and Queensland also contain significant numbers of species. The prevalence of peacock spiders across the Australian continent demonstrates they have widespread distribution within the region.

What Habitats Do Peacock Spiders Occupy?

Peacock spiders utilize a variety of habitats across Australia. Different species occupy coastal scrublands, woodlands, heathlands, deserts, alpine areas, and tropical rainforests.

Some examples of peacock spider habitat preferences:

– Maratus volcanicus – inhabits volcanic landscapes in southern Queensland

– Maratus alphonsei – found in low heathlands of Victoria

– Maratus ottoi – occupies tropical rainforests in northeast Queensland

– Maratus speciosus – lives in mallee scrublands and coastal dune systems of southern Australia

– Maratus harrisi – found in arid desert regions of Western Australia

– Maratus alpinus – native to subalpine woodlands in southeastern Australia

This diversity of occupied habitats demonstrates peacock spiders have broad environmental tolerances. They can thrive in harsh deserts as well as cold alpine zones. Peacock spiders are not restricted to a single niche habitat making them more widespread across Australia.

What Is the Abundance and Population Status of Peacock Spiders?

Unlike many rare species, peacock spiders can locally attain high population numbers and densities. In suitable habitat, dozens of individual spiders may be observed within a small area.

For example, one study in Ku-ring-gai Chase National Park near Sydney found up to 18 Maratus volans individuals per square meter in heathland areas. Another survey in the Perth region documented 34 Maratus sp. individuals per square meter in coastal scrub habitat.

However, most peacock spider species have restricted distributions, sometimes being endemic to a single mountain range or national park. Their narrow geographic ranges make them vulnerable to extinction threats like habitat loss.

IUCN Red List assessments have been completed for only five peacock spider species:

Species IUCN Red List Status
Maratus volans Least Concern
Maratus vespertilio Least Concern
Maratus speciosus Data Deficient
Maratus harrisi Data Deficient
Maratus ottoi Vulnerable

The majority of evaluated species are listed as Data Deficient, meaning not enough information is available to determine their risk status. However, the Vulnerable listing of Maratus ottoi indicates at least some species may be facing population declines and extinction risk.

More research is needed to fully assess the conservation status of peacock spiders. Their high local densities contrast with small total distribution areas. Overall populations are likely small and require habitat protection to prevent endangerment.

Do Peacock Spiders Have Any Special Protections?

There are currently no special legal protections in place for peacock spiders. No species are listed under Australian national environment law or international treaties like CITES.

However, some habitat protections likely benefit peacock spider populations. Several species occur in national parks and nature reserves across Australia. These protected lands harbor populations less vulnerable to habitat destruction.

Some experts have called for increased conservation efforts for peacock spiders, like listing threatened species under Australian law. Given their popularity and ecological importance as predators, campaigns to protect peacock spiders may find public support. But formal legal safeguards will likely only develop once more data on their conservation status is available.


So in summary, are peacock spiders rare? While locally abundant, peacock spiders have geographically restricted distributions and most species remain poorly studied. Their unique biology and appeal make them worthy of conservation. However, evidence does not indicate peacock spiders are presently rare across their Australian range. Continued scientific research and habitat protection can help ensure peacock spiders do not become rare in the future.
