Cyriopagopus sp. Sumatran tiger

Cyriopagopus sp. sumatran tiger

Cyriopagopus sp. sumatran tiger is a very beautiful bird spider due to its size, behavior and coloration from West-Sumatra. The “tiger” in her name refers to the remarkable and ongoing pattern on her abdomen, which is different than the far more famous Cyriopagopus Schioedtei. Males are brown with black legs and white bands around the joints, which is in contrast with the green and beige males of the other species from the Cyriopagopus-genus. The legs are very robust and the carapace can grow up to 3cm. Until now the bird spider hasn’t been officially published yet. The subfamily of the Ornithoctoninae (known as “earth tigers”, due to the patterns on their abdomen) mostly consists burrowing bird spiders living deep underground, except for spiders of the Cyriopagopus– and Phormingochilus-genus. The spiders are very timid and occasionally visible at night. Similar to the burrowing bird spiders from the Ornithoctoninae-subfamily Cyriopagopus often creates a tunnel system underground.


Scientific name: Cyriopagopus sp. sumatran tiger.

* Until now the bird spider hasn’t been officially published yet.

Subfamily: Ornithoctoninae.

Type: Arboreal bird spider. In captivity they often create a tunnel system underground.

Category: Old world tarantula. Not recommended for beginning hobbyists.

Urticating setae: No.

Venom: Probably strong. Depending the location of the bite and the amount of venom released, this might be a painful experience. However, no valuable scientific research has been done yet.

Origin: West-Sumatra in Indonesia.

Body length: ≤ 5-6cm.

Span width: ≤ 22-24cm.

Growth rate: Medium.

Life expectancy: Females become up to 14-15 years old. Males are given a shorter lifetime of 3-4 years.

Behavior: Because of the fact Cyriopagopus sp. sumatran tiger is a very timid bird spider, they might react very defensive towards every disturbance nearby. Adult version live high in the trees, while their younger brothers and sisters live closer to the surface between rocks, stones or even lower, adding terrestrial prey to their menu.

Accessibility (1/beginner, 10/expert): 7.


>>> First aid

Cyriopagopus sp. sumatran tiger lives in tropical humid and warm area. Both temperature and humidity are fairly constant throughout the year, with a small monsoon period from october until december. Temperatures almost daily reach levels up to 30°C. Please be informed of the fact the spider will protect itself against the burning sun in tree crevices, hollow branches, leaves and buildings. Do not overheat the terrarium. During monsoon very moist substrate from time to time is good for spiders of the Cyriopagopus-genus, but make sure no moldproblems occur.

Environmental conditions

Temperature: 25-28°C (day), 20-22°C (night).

Humidity: 70-80%.


Adult: LxWxH: 20x20x50. 2-2,5x span width in height.

Smaller than adult: 2,5x span width in height.

* Provide a piece of hollow tree trunk or cork bark. Fill it halfway with moist substrate.


Adult: 1-1,5x body length.

Smaller than adult: Minimaal 1-1,5x body length.

* The spider lives in humid area. Note that cages with high humidity levels are very sensitive for mites and other parasites. Please take your precautions.


Wet season: All year long. Throughout the year it rains 1 out of 2 or 2 out of 3 days, sometimes drying up for a few weeks.

Dry season: None.

Warmest months: None. Throughout the whole year 30°C (and more).

Coldest months: None. The coldest month don’t differ that much from the other months. Temperatures at night don’t drop underneath 20°C.

* You might like to consider an adjustment of these data with your local climate. Do not exceed minima or maxima and, if necessary, organize the year making your bird spider experience different seasons. This is very important form the moment you’d like to start breeding.


Pairings with the Cyriopagopus-genus don’t always run smoothly. In his quest for posterity, the male will show his presence relatively quick, luring the female out of her burrow. Leaving her castle she’ll probably react very aggressive/defensive towards the male, either looking for a next meal or a quick copulation. I’ve been told that if the man dies after a copulation it’s a good indication to think the copulation was successful. This however, remains a hypothesys.

• Only start breeding 4-6 weeks (or later) after the spider molted. If the female molts between pairing and cocoon, the eggs will remain unfertilized.

• Make sure the female is well-fed (not obese) before you introduce the male.

• Plan mating in autumn.

• Provide an escaping route for the male.

• Plan the pairing at the end of wet season and let the cage dry out for 2/3 months, while temperatures drop to 22/23°C. Systematically raise up temperature and humidity. This will trigger the female to start making the cocoon.

• Arm yourself with long greased tweezers. Seperate male and female immediately after mating

• From the moment you start introducing spring the female will make the cocoon. Deprive the cocoon, when desired, 6 weeks later. Store the eggs at a humidity of 100% and a temperature of 26°C. Expect 100-150 spiderlings to come out.


• “Cyriopagopus” was validly published for the first time in 1891 by the Swedish arachnologist Tamerlan Thorell?

  1. I’ll do this in English, in case you’re speaking French. I’m looking for a good forum to exchange info about tarantulas .
    I’m keeping spiders about 5 years. I’ve got 6 spiders at the moment. 2 are from the old world as they say. I’m thinking about slowly increasing the number of spiders, and eventually breeding with them. I live in the Netherlands, about 40 km from Belgium,and the fact that there is a larger community in Belgium,so I thought that I contact you if you know a good groop of dedicated keepers who are willing to share their findings with me.
    Also I would like to compliment you people on your site. Well organised, direct to the point (not to much nonsense). And it contains a lot more basic information of the different species.
    But maybe a link to a caresheat with more detailed information on basic care and especially how to deal with problems that a keeper might come across

  2. Hey Bart. First of all thank you for the compliments. We’ve spent a lot of work in this website. If you open the crossbar, you’ll notice there are quite a few informative pages on this website about basic care (and more). One of the pages is about first aid, an unicum, providing a perfect guide about first aid in arachnids ( As lots of reputable hobbyists share their experiences here, you won’t find more detailed caresheets on the web. Feel free to join our facebookgroup by opening the crossbar and clicking the facebook icon. Best of wishes.
