How to take care of Platycryptus undatus

If you want to care for your jumping spider pet successfully, know their natural habitat conditions. That way, you can provide comfortable conditions to thrive without straining with changing environment.

1.Tank Set up and Requirements

Size and space are essential aspects when it comes to your tan jumper’s tank. Experts recommend a 5-gallon tank meshed at the top for proper air circulation and to prevent soaking. In addition, fill the tank with some non-toxic substrate such as terrarium soil mix or coconut coir.

Platycryptus undatus prefers a neutral pH and up to ten hours of bright light per day. Again, it would be best to secure the lid well to prevent your spider from escaping. When it comes to light, just remember that you mustn’t place the enclosure in direct sunlight, as this will quickly cause it to overheat.

2. Give the Right Food

These spiders feed on insects but can eat nectar, berries, and pollen. Feed it with tiny insects like crickets and fruit flies. For young spiders, flightless fruit flies make an easier meal, and appropriately-sized one. Remember, food should not be more than 1.5 times the size of your spider.

Like most Jumping Spiders, this species will occasionally accept mashed-up fruit, but in my experience this is hit-or-miss. Some will and some won’t, but it certainly doesn’t hurt to try. For those that will accept fruit, you usually have to put it literally right in front of them.

Tan Jumping Spider Enclosure

Setting up a home for your jumper requires careful consideration. The size of the container you pick depends on how often you plan to take your spider out.

For instance, a smaller container will be okay if you have time to let it out daily. However, if your pet will stay in the cage for long hours, it is advisable to pick a cubic-foot container or larger.

Confining your spider in a tiny space denies it a chance to exercise, leading to a weak jumper that will likely die earlier than expected.

Furthermore, ensure adequate ventilation in your spider’s container, but avoid large holes as the spider can escape.

Tan Jumping Spider Care


A tan jumping spider thrives best in temperatures between 75 and 83 degrees F. They also prefer a low humidity not exceeding 50%. Providing this temperature in your spider’s enclosure is one way to keep them comfortable.

Diet and Feeding

Jumping spiders feed on insects, mealworms, and other smaller spiders. Thus, it is advisable to refill the food tray with fresh food daily to ensure that your pet gets a proper diet.

Moreover, it would be best to provide an insect or worm every two to three days, though some spiders can go up to a week without food. In addition, avoid giving your spider large insects.

Again, jumping spiders do not appreciate ants since they pinch them, injecting formic acid into their bodies. When feeding your spider live prey, drop it into the tank and let the jumper do its work.

Water and Humidity

A jumping spider lives best in average to high humidity, between 60 to 65%. These creatures breathe through the book lungs on their abdomen. Therefore, it would be best to put only drops of water for your pet. A lot of water can suffocate the spider when it reaches its abdomen.

Suppose you have a misting bottle; use it to apply a small mist squirt on the cage’s sides every few days. If not, drip a few drops in the enclosure through the sides. Avoid puddles, lest your pet drowns.

Tan Jumping Spider Diet

Besides the regular jumping spider’s predatory diet, a tan jumping spider also eats bits of apples, berries, and bananas. They can also feed on nectar and pollen, though not their favorite.

Therefore, consider availing a well-balanced diet of live insects for your pet to “hunt” and supplementary foods like the fruit additions. A god diet is a significant requirement for your spider’s health and longer life.

Tan Jumping Spider Male Vs Female

A mature male Platycryptus undatus is smaller than the female counterpart. When keeping more than one tan jumpers, you would better have separate tanks. While a male and female can cohabitate, keeping same sex tan jumpers will lead to a serious fight to death.

However, you must also be careful to provide sufficient food when you put a female and male together.

Tan jumpers have a complex mating where the male creates rhythmic vibrations to attract the female. Once the courtship is over, the female designs an egg sac where it lays its eggs.

Tan Jumping Spider Poisonous

A tan jumping spider is not poisonous, though sometimes it can bite in defense. It is a friendly creature that you can handle and keep as a pet.

However, if it bites you, you may experience mild symptoms like itching, redness, or swelling. If these symptoms persist, seek medical attention as you may be allergic to the otherwise harmless venom.


A tan jumper has a generally short lifespan of about one to two years. Like other jumping spider species, the female lives slightly longer than its male counterpart.

However, their population remains relatively high as they mature fast and reproduce for up to three times in a year. A tan jumper’s life cycle consists of egg, spiderling, juvenile, and adult stages.

Temperament and Handling

A tan jumper is relatively gentle and calm, but it can be shy. If you scare them or they feel threatened, it may try to hide. While they are friendly with humans, they can be aggressive regarding sharing space with other animals.
