Yellow-Spotted Isopod, 10 Count
This listing identifies the animals as medium-sized Armadillidium gestroi, approximately one-half inch, with dark bodies and bold yellow spots. It describes them as useful for terrarium cleanup and as food for reptiles and amphibians. The count includes adults and juveniles; babies do not count toward the stated quantity.
Best for: Buyers who want clear species and appearance details, or who are comparing a colony animal with a feeder option. The listing also notes that the isopods are active, often nocturnal, and may hide or burrow when given objects and substrate.
Limitation: The seller cautions against ordering during extreme hot or cold weather and says packages should not be left outdoors or in mailboxes. Consider a shipping hold or delaying an order in severe temperatures.
Gestroi Isopods, 12 Count
This 12-count listing describes yellow-and-black Armadillidium gestroi that roll into a ball when disturbed. It presents the group as a starter colony intended to establish and reproduce over time. The listed diet includes mold, decaying plant matter, leaf litter, and animal waste, making the isopods a potential cleanup crew for bioactive terrariums and vivariums.
Best for: Keepers seeking a group for a bioactive display and interested in establishing a colony. Choose this if the stated quantity and cleanup role matter more than a detailed size or lifespan description.
Limitation: The supplied product details do not state a specific lifespan or shipping-temperature guidance. Check the listing for current care and delivery information before ordering.
Yellow-Spotted Gestroi, 12+
This listing offers 12 or more yellow-spotted Armadillidium gestroi for bioactive terrariums, vivarium cleanup crews, or reptile food. Its description says the animals consume waste buildup in terrarium bedding and other reptile substrates, and characterizes them as fast-producing.
Best for: Buyers who want a stated minimum count above 12 or need isopods for either cleanup or feeder use. It is a direct species match for shoppers specifically searching for yellow-spotted isopods.
Limitation: The product details provided do not specify adult-to-juvenile proportions, shipping precautions, or individual care conditions. Confirm these points with the seller if they affect your setup.
Orange Dalmatian Isopods, 10
This option is Armadillidium vulgare Orange Dalmatian, not yellow-spotted A. gestroi. The listing describes its use in bioactive terrariums and vivariums, where the isopods break down mold, waste, and decaying matter. It also identifies display vivariums and color-focused collecting as intended uses.
Best for: Buyers open to a different species and orange Dalmatian coloration who still want a cleanup crew. It is included as a color-oriented alternative, not as a substitute for the requested species.
Limitation: Avoid this choice if you specifically need yellow-spotted Armadillidium gestroi; the listed species and color morph are different.
Orange Isopod And Springtail Bundle
This bundle combines 100 or more orange isopods with 10 Florida Orange springtails. The listed isopod mix includes Porcellio laevis “Orange,” Porcellio scaber “Orange,” and Porcellionides pruinosus “Powder Orange.” The description assigns isopods a role in breaking down decaying plant matter and waste, while springtails consume mold and fine debris.
Best for: Keepers seeking a mixed cleanup crew with both isopods and springtails. The combination is intended to provide different cleanup roles in one bundle.
Limitation: This is not a yellow-spotted A. gestroi product. Choose it only if a mixed orange cleanup crew meets your needs.
Buying Guide: Choosing Yellow-Spotted Isopods
How do you confirm the species?
Look for the scientific name Armadillidium gestroi as well as the common descriptions “yellow-spotted” or “clown isopod.” Common names alone can be less precise. The Orange Dalmatian and orange mixed-species listings above are alternatives, not listings for the same species.
What quantity should you compare?
Compare the stated count and whether it includes mixed ages. One listing specifies adults and juveniles and says babies do not count toward the quantity; another states 12 or more. A larger stated count may suit buyers who want more animals at the start, but listing details do not guarantee a particular colony outcome.
Are they for cleanup or feeding?
The three A. gestroi listings describe terrarium cleanup uses, and two explicitly mention feeder use. Select according to your intended purpose and verify that the animal is appropriate for your specific enclosure or feeding plan.
What should you check before live-animal shipping?
Review delivery timing, weather guidance, and pickup options. One seller specifically warns against extreme temperatures and packages left outside or in mailboxes. Because shipping guidance can differ among listings, check the selected seller’s current instructions.
