Emperor Scorpion Feeding: Schedule, Diet, and Why Fasting Is Normal
Emperor scorpion feeding is genuinely low-effort once you internalize the one fact that changes everything about how often you should be doing it: this species can comfortably go far longer between meals than most keepers assume.
Emperor Scorpion Feeding: Schedule, Diet, and Why Fasting Is Normal
Emperor scorpion feeding is genuinely low-effort once you internalize the one fact that changes everything about how often you should be doing it: this species has a slow metabolism and can comfortably go far longer between meals than most keepers assume. For the rest of their care needs, see our complete Emperor Scorpion care guide.
The Staple Diet
Emperor scorpions are obligate carnivores, and gut-loaded feeder insects make up the entire diet. Crickets and dubia roaches are the most reliable staples, with locusts and the occasional mealworm or superworm added for variety. Adults use their powerful pincers to tear prey apart rather than relying on the stinger, which is really more of a last-resort defensive tool for this species.
Feeding Frequency and Portions
Size prey to your scorpion's body, nothing larger than the abdomen. A practical portion is 3 to 4 crickets or the equivalent at a time. Frequency depends heavily on age and life stage:
- Juveniles and nymphs: every 2 to 4 days, they're growing and genuinely more voracious.
- Adults: once a week is standard, sometimes 2 to 3 insects offered weekly.
Emperor scorpions can safely fast for a month or two, especially heading into a molt, and refusing food during that window is normal, not a sign of a problem. Always remove any uneaten prey within 24 hours, live insects left in the enclosure can stress or injure a resting or molting scorpion. A good rule of thumb for adjusting frequency: an abdomen that looks narrower than the carapace means feed a bit more; a visibly distended abdomen means it's time to cut back.
Foods to Avoid
Never feed wild-caught insects, pesticide and parasite risk are both real concerns. Fireflies are genuinely toxic to scorpions and must never be offered. Skip human or table food entirely, scorpions are built to digest liquefied insect prey, not processed food. And avoid prey that's too large for your scorpion to subdue safely.
Supplementation
None needed directly. Instead of supplementing the scorpion, supplement the food: gut-load feeder insects with fresh produce or a commercial gut-load for at least 24 hours before offering them, this is genuinely how nutrition gets to your scorpion in this species.
The Mistakes That Actually Matter
Overfeeding is the real risk here, obesity is a documented, common problem in captive scorpions, and because this species needs so much less food than its constant hunting behavior might suggest, it's easy to offer more than it actually needs.
The second mistake is leaving live prey in the enclosure too long, an uneaten cricket can genuinely injure a molting or resting scorpion if it's not removed within a day. Feeding wild-caught insects or, worse, fireflies specifically, introduces a real poisoning or parasite risk that's entirely avoidable by sourcing feeders properly.
