Emperor scorpions (Pandinus imperator) eat live or pre-killed invertebrate prey. The birthday feast is appropriately sized crickets, dubia roaches, or mealworms, offered once the scorpion is confirmed to be in active feeding condition and not in premolt or post-molt recovery. The molt timing rule is the same as for tarantulas: never offer prey to a scorpion in premolt or immediately after a molt. The exoskeleton needs time to fully harden before the scorpion can safely hunt and consume prey.


What Emperor Scorpions Can Eat at a Birthday Party

Crickets. The most widely available and consistently accepted feeder for emperor scorpions. Adult P. imperator can take adult crickets. Pre-kill if the scorpion doesn’t strike within a few minutes of introduction, a live cricket can bite a molting or recently molted scorpion.

Dubia roaches. Excellent nutritional profile. Accepted by most emperor scorpions. For the birthday feast, a medium dubia is a quality feeder choice.

Mealworms. Lower nutritional value but accepted. Fine as part of a birthday variety spread.

Superworms. A larger, more calorie-dense feeder for the birthday treat component.

Pre-killed approach. Crush the feeder insect’s head before offering to eliminate any remaining movement that might bite the scorpion. Use feeding tongs. This is the safer approach for all scorpion feeding and particularly for the birthday feast.


The Molt Timing Rule (More Important Than the Birthday)

Emperor scorpions molt periodically as they grow. The exoskeleton is soft after a molt and the fangs are non-functional. A scorpion offered prey while in this state can be bitten by the prey item with no ability to defend itself.

Signs of premolt: loss of appetite for several days to weeks, the scorpion becoming inactive, spending more time in the hide.

If premolt signs are present on the birthday: remove all prey from the enclosure and wait. The birthday feast happens after the molt completes and the exoskeleton has fully hardened, which takes at minimum several days and up to two weeks for a large adult.

The birthday feast is secondary to the molting process. Don’t force a feeding for the birthday if the scorpion is in premolt.


What Emperor Scorpions Cannot Eat

Wild-caught insects. Pesticide exposure risk. Captive-bred feeders only.

Prey too large for the scorpion. The prey item should be no larger than the scorpion’s body without the tail. Oversized prey creates injury risk.

Any food during or immediately after molt. The molt period has no exceptions for birthday celebrations.

Plant matter. Emperor scorpions are obligate invertebrate predators. No fruit, vegetables, or any plant material.

Emperor scorpions hunt primarily with their claws rather than their stinger, which is why they prefer prey they can subdue with grip alone. The birthday prey should be small enough for this approach. Photo: Kevin Walsh / Wikimedia Commons. CC BY 2.0.

The UV Birthday Photo

Under ultraviolet (blacklight) at approximately 365nm wavelength in a completely dark room, emperor scorpions fluoresce bright blue-green. The birthday UV photo setup:

  1. Turn off all lights
  2. Hold a UV torch above or beside the enclosure
  3. Photograph without flash

This photo is the community’s most-shared emperor scorpion birthday content and requires no handling. The feast happens separately.


FAQ

How often do emperor scorpions eat?

Adult emperor scorpions eat every 7 to 14 days. The birthday feast is the scheduled feeding for that week, not an extra one.

Can I feed my emperor scorpion a waxworm on the birthday?

Yes, in small amounts as a treat component. Waxworms are high-fat and should be supplementary, not the primary feeder. One waxworm alongside the main cricket or dubia offering is birthday-appropriate.

My emperor scorpion ignored the birthday prey and retreated to its hide. What happened?

The most likely cause is premolt preparation. A scorpion that stops eating and becomes inactive is probably approaching a molt. Remove the prey and let the scorpion proceed on its schedule. The feast can wait.
