Jumping spiders are fascinating creatures, known for their vibrant colors, exceptional eyesight, and surprisingly charming personalities. Many people are drawn to keeping them as pets due to their captivating hunting behaviors and relatively low-maintenance care. However, providing the right diet is crucial for their health and longevity. This guide will delve into the best foods for your jumping spider, addressing common concerns and misconceptions.
What do jumping spiders eat in the wild?
In their natural habitats, jumping spiders are voracious predators, primarily subsisting on insects. Their diet consists largely of:
- Flies: These are a staple food source, providing essential nutrients. Smaller species like fruit flies are ideal for spiderlings, while larger houseflies suit adult spiders.
- Other small insects: Crickets, mealworms (occasionally, as a treat), and other small invertebrates are suitable options. Avoid insects that are larger than the spider's body, as they can be difficult to subdue and may injure the spider.
- Small spiders: While cannibalism is possible, it’s not their preferred food source and shouldn't be encouraged.
What kind of insects are best to feed my jumping spider?
The ideal insect for your jumping spider depends on its size and age. Here's a breakdown:
- Spiderlings: Tiny fruit flies ( Drosophila melanogaster or Drosophila hydei) are perfect for spiderlings. They are small enough to be easily captured and provide the necessary nutrients for growth.
- Juvenile spiders: As your spider grows, you can gradually increase the size of its prey. Small crickets or flightless fruit flies are suitable options.
- Adult spiders: Adult jumping spiders can handle larger insects like houseflies, bluebottle flies, or small crickets. Ensure the prey is not too large to prevent injury to the spider.
How often should I feed my jumping spider?
Feeding frequency depends on the spider's age and size. Generally:
- Spiderlings: Need to be fed daily or every other day.
- Juvenile spiders: Should be fed every 2-3 days.
- Adult spiders: Can be fed every 3-5 days, or even less frequently if they have a large meal.
Always remove any uneaten prey after 24 hours to prevent the enclosure from becoming unsanitary.
What should I NOT feed my jumping spiders?
Some insects should be avoided entirely:
- Wild-caught insects: Wild-caught insects may carry pesticides or parasites that can harm your spider. It's always safer to use commercially bred insects.
- Insects from outside your home: These are likely to have been exposed to chemicals, diseases, or parasites.
- Large or aggressive insects: Insects that are too large or aggressive for your spider to handle can injure or even kill it.
- Insects with hard exoskeletons (e.g., beetles): These can be difficult for jumping spiders to digest.
Can I feed my jumping spider other things besides insects?
No, jumping spiders are obligate carnivores, meaning their diet must consist entirely of animal matter. Do not attempt to feed them plant material, fruit, or any other non-insect food.
How do I introduce food to my jumping spider?
Simply place the live prey in the enclosure. Jumping spiders are excellent hunters and will quickly locate and capture their food. Avoid handling the insects with your bare hands, as you could inadvertently transfer harmful substances.
My jumping spider isn’t eating. What should I do?
If your jumping spider refuses food, there could be several reasons:
- It's recently molted: Jumping spiders are vulnerable after molting and may not eat for a few days.
- It’s not hungry: Adult spiders can sometimes go several days without eating.
- The prey is inappropriate: Ensure the size and type of prey are suitable for your spider.
- Environmental conditions: Check the temperature and humidity levels in the enclosure.
- Illness: If your spider refuses food for an extended period, it may be ill and require veterinary attention (though finding a specialist might be difficult).
By understanding their dietary needs, you can ensure your jumping spider thrives and provides you with years of fascinating observation. Remember to prioritize safety and hygiene when feeding your pet to keep both you and your spider safe and healthy.
