Distribution and habitat

The venomous Brazilian Jewel Bird Spiders are crepuscular to nocturnal ground dwellers. They are native to the dry and rain forests of Brazil. There they live hidden between roots, mostly in self-dug burrows.

Maintenance

For 1 animal a terrarium with a minimum size of 40 x 30 cm and a minimum height of 40 cm can be recommended as a guideline. The terrarium should be placed in a quiet place without sunlight.

You need a terrarium structured with vertical cork tubes, roots and branches (hiding places), a solid, 10-15 cm deep substrate of sand-loam-peat mixture, a small, shallow drinking vessel and for decoration artificial or potted plants (e.g. Ficus repens, Scindapsus aureus). A large part of the substrate should always be kept slightly moist. Daily, the inside of the terrarium should be finely sprayed with water (humidity), but a rain or mist system is better.

Temp. day: 20-24 °C

Temp. night: 18-22 °C

Humidity: 60-80

The lighting duration should be 8-12 hrs. depending on the season. A conventional light source (fluorescent tube, incandescent bulb) is sufficient. Special lamps with high UV content are not necessary.

Diet

The food supply should consist of crickets, cockroaches, house crickets, maggots and grasshoppers and other arachnids. Adult animals can also be offered nest young mice. The prey animal is injected with a digestive juice with the biting tools (chelicerae), which liquefies the protein components and the prey can be sucked out (extracorporeal digestion). Young animals can be offered food 1-2 times a week, adults only every one to two weeks. Under no circumstances should they be overfed, the basic rule being that the abdomen should be no more than 1½ times the size of the cephalothorax. Unaccepted food must be removed after 1-2 days. Refusal of food may indicate a natural phase of starvation or an impending molt. No food animals should be in the terrarium during molting, they could injure the spider

A regular and varied diet promotes health and prevents deficiency symptoms.

Reproduction and breeding

The smaller males can be recognized by their bulbs folded in towards the body. The female lays several 100 eggs in her burrow lined with webs 4-5 months after mating. The eggs are spun into a dense cocoon in which the larvae develop and are guarded by the female. After the third molt, the young leave the burrow and feed on their own. Females can live up to 20 years.

Obligation to report

Make sure to inform yourself about any regulations on keeping or bans on keeping this animal in your state or home municipality (e.g. public order office). Your pet store will be happy to provide you with further information.

Important

They are temperamental and sensitive to disturbances. In defense, they hurl irritant hairs with their hind legs against the attacker (bombard). These cause skin irritation and may cause corneal damage in the eyes as well as asthma-like symptoms. Care should also be taken when cleaning the terrarium, as irritant hairs can be stirred up from the substrate (protective goggles)

A bite is very painful, the poison corresponds to that of a bee or wasp.

Crushed or held legs can be thrown off at a predetermined breaking point and regenerate completely after 1-2 molts.

Before purchasing, a terrarium should be prepared that meets the species specific needs. Good ventilation without drafts and equipment for measuring temperature and humidity are necessary. The lighting has to correspond to the species-specific day-night rhythm and should be placed in such a way that the animals cannot injure themselves. The terrarium should be locked in such a way that neither unauthorized persons can open it nor the animals can escape. Special attention must be paid to thorough hygiene and impurities must be removed regularly.
