Can (And Do) Jumping Spiders Eat Mealworms?


If you’re reading this article, then your most likely wondering if jumping spiders eat mealworms and if so, do they have any health benefits?

Well, we can safely say that jumping spider do eat mealworms! In fact, mealworms are a great source of protein and fat that can aid in their growth and development “but only” if fed in correct moderation.

Because mealworms contain a lot of fat, they should only make up about 20% of a jumping spider’s diet. Feeding them too many mealworms can lead to health problems, such as obesity and digestive issues.

A varied diet is important for the health of your jumping spider, so consider offering them a variety of small insects in addition to mealworms.

How Often Can Jumping Spiders Eat Mealworms?

While mealworms are a nutritious option for jumping spiders, it’s recommended that they are not fed exclusively all the time, and definitely not while they’re in the molting stage.

Jumping spiders are very sensitive and fragile when they are going through the molting stage! So much so, that even their prey “in this case, mealworms” can injure them, and in some cases, be fatal.

Personally, we found that jumping spiders typically enjoy eating mealworms once or twice a week. But, only in moderation, and in combination with other small insects! This way you’re providing them with a diverse range of nutrients and ensure their continued good health.

Just remember, feeding your jumping spider a well-balanced diet is crucial to maintaining their overall health and promoting successful molting.

Why Some Spiders Prefer Live Prey

Some spider species prefer live prey because it provides more of a thrill and challenges their hunting skills. For example, jumping spiders are known for their agility when hunting, and some enjoy stalking and catching live prey.

This is because the movement of live prey triggers the spider’s innate hunting instincts and stimulates their brain in a way that dead prey cannot.

Additionally, the act of hunting live prey creates a sense of satisfaction for the spider, which can lead to a better overall experience for them.
