Mealworms are an excellent supplementary food for jumping spiders, but it is important to keep in mind that mealworms are high in fat and do not provide the highest nutritional value. In addition, they can also be harmful for jumping spiders, as they can transform into beetles and cause injury. For these reasons, mealworms should only be fed to your jumping spider once they are dead. It is also important to keep a close eye on your spider when it is eating.

Mealworms should make up about 20% of a jumping spider’s diet. The right amount will depend on the size of your pet. Ideally, a spider’s abdomen is about one and a half times its carapace. A round or elliptical abdomen indicates that it is well fed, while a sunken abdomen indicates dehydration.


Crickets make excellent feeders for jumping spiders and can be purchased from pet stores. They are available in many different sizes from micro crickets to large, predatory crickets. These insects are low in calories and have substantial amounts of protein and nutrients. They are also very active, which makes them a healthy choice for your jumping spider. You can also choose to feed your jumping spider mealworms, which are cheap and sustainable.

While many people recommend crickets as a safe and easy to maintain food source, you should remember that they are not a good choice for all jumping spiders. Crickets are known to be aggressive towards spiders and can harm the molting process. In addition, you should avoid feeding crickets to an older spider.


Flies are excellent feeders for jumping spiders, and they are readily available at pet stores and online. They can also be purchased at an angler’s store for a very low cost. One of the best options is to buy cultured flightless fruit flies, which are the size of crickets. They have a very short lifespan, and can even be bred in a plastic tub setup.

Whether you choose to feed your jumping spider mealworms or flies, you’ll need to carefully monitor its appetite. Although flies can be a good source of protein, a high-fat diet will not be good for your spider. A good rule of thumb is to use flies every other day. Flies can be purchased in pet stores or online, and fly larvae are available in fishing stores as well.


Most jumping spiders will feed on ants, but some of them will hunt other animals as well. Jumping spiders are known to feed on ants because they look and move like ants and are very difficult for predators to spot. These spiders have long bodies and four pairs of eyes in the front of their head. They may be difficult to see, but they are quite observant, and can spot their prey with ease.

You can feed a jumping spider a variety of different types of insects, such as ants and other insects. You should avoid red and fire ants because they contain venom that can be dangerous to humans. Other types of insects that jumping spiders may eat include grasshoppers, mealworms, flies, and moths.


Jumping spiders are known to feed on all kinds of insects. However, you should make sure that you are not giving them the same food every day. If you are feeding your spider only grasshoppers, it is better to alternate with other insects like crickets and flies. Alternatively, you can try mealworms, which are also suitable for feeding your jumping spider.

A jumping spider needs to be fed about three times a week. It can eat a variety of insects, and its diet includes beetles. It is also possible to buy captive jumping spiders, though you should note that you are removing it from its natural habitat. However, these spiders are harmless to people when not provoked. Adult jumping spiders usually stalk their prey before pouncing on it.
