Expansus, reimagined in fall color.
Autumnal Equinox isopods (Porcellio expansus) carry the same massive, flared frame as the standard Expansus but in a warm seasonal palette that makes this morph stand out even among giants. They share the same Spanish origin and dry-leaning needs as their relatives, wanting very high calcium and a setup held at 68 to 78F with 45 to 65% humidity. This is a slow-building, high-value colony worth the patience it takes to establish.
- Rare seasonal color morph of the giant Expansus
- Dramatic flared body plates
- Dry-leaning, very high calcium requirements
- A prized addition for the advanced collector
Covered by our Live Arrival Guarantee.
