One of the most important things when owning a jumping spider is their diet! And feeding them the wrong foods can be unhealthy, and cause problems later on down the road.
Many pet owners know that feeding spiders “live insects” can be a huge benefit. However, one question that’s often asked, “especially by new owners” is whether or not, jumping spiders can eat dead insects.
The short answer is yes! jumping spiders will eat dead insects. However, its important to note that dead insects don’t provide the same nutrition as “live prey” and some may refuse to eat them altogether!
Do Wild Jumping Spiders Eat Dead Insects?
Wild jumping spiders “Salticidae“ are known to be fierce hunters, but when it comes to feeding, do they opt for fresh prey orwill there eat dead prey?
Studies have suggested that jumping spiders do, in fact, consume dead insects in the wild. While this may be surprising, it makes sense considering the unpredictable nature of hunting and the need for sustenance.
When it comes down to it, jumping spiders are opportunistics, and will take full advantage of any available food source, including insects that are dead. Here’s why…
- Limited resources: In some areas, jumping spiders may have limited access to live prey due to environmental factors like drought or cold temperatures. Eating dead insects can help them survive when other food sources are scarce.
- Lack of mobility: As jumping spiders age, they become less mobile and may not be able to hunt for live prey as easily. Eating dead insects is an easier way for them to get the nutrition they need in order to survive.
- To supplement their diet: Sometimes when a jumping spider catces a insect they will not eat it stright away. Some will accally save it for later at which point the insects will be dead. However, this helps the spider supplement their diet, and reduce competition from other spiders in the area.
So while jumping spiders may eat dead insects, they will only do this if they are hungry enough.
Should You Feed Dead Insects To Your Pet Jumping Spider?
If you have a pet jumping spider, you may be wondering if it’s okay to feed them dead insects.
Well, if you have an endless supply of live prey, then its recommended that you feed your pet spider live insects as it provides the most nutrition.
However, if you don’t have access to live prey, small amounts of dead insects (dried insects) can supplement their diet as an alternative.
But, as before, live prey is generally “recommended” as the preferred food choice for jumping spiders.
Another thing to consider is the amount of dead insects to feed your jumping spider! As before, dead insects don’t supply enough nutrition as live insects, and feeding them too many can be harmful.

For example, the Habronattus species is known to feed on flower nectar and pollen in addition to insects. On the other hand, the Salticus scenicus species is known to feed primarily on flies.
Age And Gender
The age and gender of jumping spiders also play a role in their diet. Younger spiders require more protein in their diet, while older spiders may eat less or have a broader diet.
Additionally, female jumping spiders may have different dietary needs than males, especially during mating season when females require more energy to produce eggs.
Availability Of Prey
The availability of prey in a jumping spider’s habitat also affects their diet. If a particular food source is prominent in one area, then the jumping spiders there will adapt to eat it.
For example, if there is an abundance of flies in an area, jumping spiders in that area may feed primarily on flies. However, if the availability of prey changes, jumping spiders may switch to other food sources.
So yes, jumping spiders can eat dead insects, however, its not recommended if you have plenty of live prey at your disposal. If your ever in doubt remember to contact your local pet shop as they can advise you on what to do.
