Chinese Hourglass Spider (Cyclocosmia ricketti)

Meet the Chinese Hourglass spider! It’s part of the Halonoproctidae spiders family and has a super unique look with a special disk at the end of its tummy. Join us as we share awesome facts about this one-of-a-kind spider!

Scientific Classification

Chinese Hourglass Spider

Physical Description and Identification

Adults

  • Size: Male: 2.1 cm Female: 2.5-3 cm
  • Color: These spiders are generally brown in color.
  • Other Characteristic Features: The abdomens of these spiders abruptly end in a rigid disk of around 3.2 cm in diameter, which resembles a copper coin. Due to this distinct feature, they are popular as pets.

Cyclocosmia ricketti

Eggs

The eggs are laid inside the caves, which they protect by using the coin-shaped disk on their abdomen to block the entrance to their burrow, in a process called phragmosis.

Spiderlings

As spiderlings are rarely seen outside the tunnels, very little is known about their appearance. They emerge from the burrow after they mature.

The Web

Like other trapdoor spiders, they are not great at constructing webs. They use the silk threads they generate to line their tunnels.

Are Chinese Hourglass Spiders Venomous?

Yes, Chinese Hourglass spiders have venom. They use it to catch their food, like tiny bugs. Most people don’t need to worry about it.

Can Chinese Hourglass Spiders Bite?

They sure can! But these spiders are usually not aggressive. They might bite if they’re really scared and their bite is painful.

Ecological Importance and Behavior of Chinese Hourglass Spider

The Chinese Hourglass spider contributes significantly to the control of insect populations, serving as natural pest management. Their unique burrowing and defensive behaviors also play a role in soil aeration and nutrient cycling.

Natural Predator: Natural predators such as scorpions and parasitic wasps pose a threat to these spiders, often breaching their burrow defenses.

Prey-Predator Dynamics: As predators, Chinese Hourglass spiders help maintain a balanced ecosystem by controlling insect populations. Their own survival tactics, including the distinctive use of phragmosis, are a testament to the evolutionary arms race between predators and prey.

Relationship with Humans: Humans rarely encounter these elusive spiders, but their rarity and unique appearance have made them highly sought after by collectors, impacting their numbers in the wild. The ethical implications of their trade and collection highlight the need for conservation efforts.

Cyclocosmia ricketti Spider

Did You Know

  • They are a scarce species, with only six specimens seen in the wild from 2000 to 2016. This has led to a collector’s market for these spiders, leading to farms in Thailand breeding and selling them. As of January 2021, these spiders have sold for $3860 or 25,000 yuan per specimen.
  • South African phycologist Mary Agard Pocock first described this species in 1901.

In summary, the Chinese Hourglass spider is not just an arachnid with an intriguing appearance; it plays a pivotal role in its ecosystem.
