Eurycotis floridana
A large nocturnal cockroach that ranges across the damp terrestrial edges of miniBIOTA processing leaf litter and decaying plant matter, Florida Woods Cockroaches confirmed a second generation inside the closed system when a juvenile was observed in the Mangrove Forest in April 2026.
Population has been supplemented through multiple intentional additions: July 2025 (initial), October 2025 (five more, total ~8), March 17, 2026 (one adult, ~3), April 12, 2026 (one adult, ~4). An egg case was observed forming January 24, 2026. A juvenile was confirmed in the Mangrove Forest on April 22, 2026, alongside a deceased adult found in a Red House Spider web. Exact current count is uncertain; estimated four adults as of April 12, with subsequent losses to predation unquantified.
Feeds primarily on dead and decaying plant matter, leaf litter, bark, and woody organic debris across the terrestrial biomes of miniBIOTA. Nocturnal foraging carries individuals across Mangrove Forest, Lowland Meadow, Lakeshore, and Marine Shore edges. Their frass and feeding activity return nutrients to the litter layer and soil, contributing to decomposition pathways in the closed system.
Requires warm, humid terrestrial conditions. Cold-sensitive: documented cold-stunned at approximately 50°F in miniBIOTA. Tolerant of tropical temperature swings in its normal range but not suited to prolonged cool conditions. Depends on damp substrate and high relative humidity rather than open water.
Egg case formation was observed in the Mangrove Forest on January 24, 2026 (video). A juvenile was directly confirmed on a Mangrove Forest branch on April 22, 2026 (video), representing the first second-generation individual of this species in miniBIOTA. Whether that juvenile has survived to adulthood is unconfirmed. Spider predation was also confirmed on the same date.
Processes dead and fibrous plant matter that accumulates in the leaf litter layer, returning organic material to decomposition pathways in the terrestrial realm. In miniBIOTA, their movement across the atmosphere reservoir system may also interact with the rain infrastructure, as cockroach weight on suspended reservoirs was hypothesized to have contributed to triggering the first rain event in the sealed system on February 8, 2026 (causation not confirmed).
Follow this species across the habitats where it currently appears in the miniBIOTA biosphere.
