Whether you’re an arachnid expert or just starting out, this discussion will uncover new insights into jumping spider behavior.

Let’s satisfy your curiosity on what these tiny hunters actually want to devour!

Will Jumping Spiders Eat Dead Insects?

Yes, Jumping spiders will eat dead insects, although they prefer live prey when possible. As opportunistic hunters, jumping spiders will consume any small arthropods they can overpower.

This includes various flies, ants, Isopods, mosquitos, moths, crickets, beetles, and other spiders. If a jumping spider happens upon a freshly dead insect, it will readily eat the corpse as long as the body hasn’t begun decomposing.

Jumping spiders rely heavily on movement to identify and stalk prey. They are less likely to recognize or consume insect carcasses that have been dead for a prolonged period.

Still, a hungry jumping spider will resort to scavenging if no other food sources are available.

What Insects Do Jumping Spiders Eat?

Jumping spiders are not picky eaters and they will consume most small insects and arthropods they can capture. Preferred prey includes flies, moths, mosquitoes, butterflies, beetles, grasshoppers, crickets, and other spiders.

Jumping spiders are generalist predators and they will eat any insects small enough for them to overpower. The size and availability of prey dictates their diet.

Jumping spiders (Salticidae) have excellent eyesight and stalk their prey slowly before pouncing and injecting venom. They do not spin webs to catch food like other species of spiders. Their diverse diet allows jumping spiders to thrive in most environments from forests to deserts.

Are Dead Insects Bad for Jumping Spiders

Eating dead insects / bugs does not appear to pose an immediate health risk to jumping spiders. Nonetheless, decaying insect carcasses do not provide optimal nutrition compared to live prey.

Dead bugs likely have lower levels of moisture and fats that are essential to a jumping spider’s diet.

There is also some risk of consuming pathogens or toxins from decaying bodies. So while an occasional dead insect meal won’t harm them, jumping spiders seem to prefer freshly killed or live prey.

Providing jumping spiders with a varied buffet of live insects is ideal for their health and growth. If dead prey is their only option, the fresher the better.

Important Questions

Will spiders eat fallen limbs from prey insects?

Yes, spiders will eat fallen limbs and other body parts from prey insects. After catching and killing insect prey, spiders will often leave behind legs, wings, antennae and other appendages that they are unable to consume.

However, spiders will not let this organic matter go to waste. The spider will return and eat these leftover insect parts which still contain nutrients.

Web building spiders in particular will reuse their own webs to collect these insect leftovers. The fallen limbs get caught in the sticky silk, allowing the spider to come back and eat them.

This grants the spider further nutritional value from a single prey item.

Do spiders eat their dead?

No, Spiders do not typically eat their own dead. There are a few rare exceptions, such as if a female dies while guarding her egg sac, other spiders may consume her body to prevent rotting near the eggs.

In general spiders avoid cannibalism and do not feed on other dead spiders. There are a few reasons for this. First, spiders use pheromones and vibrations to recognize living prey or potential mates.

These chemical signals quickly fade after death, making dead spiders unappealing. Second, a dead spider’s abdomen can burst open, making it hazardous to eat. The fluids released during this rupture contain unpleasant compounds that repel other spiders.

Spiders avoid eating their own kind because cannibalism can spread diseases.

For these reasons, spiders discard or ignore bodies of other dead spiders.

The lack of cannibalism may also explain why spiders do not usually attack each other and can live in close proximity within a web. Clearly spiders find other living or dead insects to be more appealing meals.
