Centruroides hentzi
A nocturnal hunter across miniBIOTA's terrestrial habitats, the Hentz Striped Scorpion stalks crickets and small invertebrates after dark and hides under bark and debris by day; introduced as a mating pair in 2025, the species produced a first brood that same year.
Hentz Striped Scorpions hunt small invertebrates at night and shelter beneath bark and litter by day. Two founders produced young in 2025. Red House Spiders later took scorpions, and about one was believed to remain by August 2026; the number has not been confirmed by a dedicated census.
Centruroides hentzi is the most common scorpion in Florida, found statewide in hammocks, gardens, scrub, and suburban environments. It shelters beneath bark, in leaf litter, under debris piles, and in any dark, humid crevice during daylight hours, emerging after sunset to hunt. The species is an ambush and pursuit predator, feeding on crickets, roaches, spiders, isopods, and other arthropods that venture within reach. Prey is seized with the pedipalps (claws) and stung with the tail if resistance is significant; the venom immobilizes small prey quickly.
The Hentz Striped Scorpion fluoresces visibly under ultraviolet light, a trait shared with all scorpions and caused by fluorescent compounds in the cuticle. This makes targeted nighttime detection straightforward with a UV lamp. In Florida, the species is common enough to be encountered incidentally in gardens and building margins.
Reproduction is viviparous: females do not lay eggs but carry developing embryos internally and give birth to live young. Newborns are pale and soft, and they immediately climb onto the mother's back, remaining there through their first molt before dispersing as independent juveniles. Females may produce one or more broods per year under favorable conditions. Growth is slow; individuals pass through multiple molts before reaching sexual maturity. Lifespan is estimated at three to five years in wild populations.
The Hentz Striped Scorpion occupies the nocturnal apex predator position in miniBIOTA's terrestrial food web. No larger terrestrial predator is present in the system; the species' own predators are larger arachnids. By hunting crickets, roaches, and other invertebrates, the scorpion regulates prey population density in the Lowland Meadow, Mangrove Forest, and the Lakeshore (a long-standing range first documented August 3, 2026), moving prey biomass into a long-lived, slow-reproducing predator layer.
At five individuals on record, the population was Vulnerable; as of August 3, 2026 it is believed to have declined to approximately one individual. Second-generation individuals added resilience but also faced predation from the Red House Spider, which had already consumed at least one juvenile in an earlier, separately documented instance. The decline from five to approximately one is now confirmed to have been caused the same way: scorpions caught in Red House Spider webs and eaten. The exact dates and number lost remain unknown.
Two founding scorpions were introduced in 2025 and produced a brood. Molts show that some young survived beyond the first instars; spiders took at least one juvenile.
May 5, 2025: First individual introduced.
July 2, 2025: The second founding individual was introduced; the two later bred.
September 2, 2025: The first brood was noticed.
Early growth: Several shed exoskeletons showed that young scorpions continued molting. One juvenile was caught and eaten by a Red House Spider. Other early feeding and relocation events have no established dates.
March 26, 2026: A scorpion was seen in Prairie after a long gap without sightings. Two had previously been seen, but the number then remaining was uncertain.
August 3, 2026: About one individual was believed to remain, compared with an earlier estimate of five; this was not a dedicated census.
Later assessment: About one was still believed to remain. Earlier sightings included an original adult and a growing offspring, but the offspring's maturity was not established. Web predation caused losses; exact dates and the number taken remain unknown.
Two founders produced a brood and young survived through later molts. Earlier estimates reached five, but about one was believed to remain in August 2026; no dedicated census confirmed the number. Red House Spider web predation caused losses, although exact dates and numbers are unknown. An original adult and a growing offspring had been seen earlier; the offspring's maturity was not established.
Nocturnal active predator that hunts crickets, roaches, isopods, and other small invertebrates by ambush and direct pursuit through the Lowland Meadow, Mangrove Forest, and Lakeshore. In miniBIOTA, one juvenile was found caught in a Red House Spider web and consumed; this is the only directly observed predation event in observation records. Multiple molted exoskeletons have been found, indicating that second-generation individuals are growing through successive instars. Direct feeding behavior on invertebrate prey has not been documented in an archived observation, though the species' diet in the wild is consistent with the invertebrate community available in the terrestrial biomes.
Broadly adapted to Florida's subtropical conditions, including warm temperatures and moderate to high humidity. Requires suitable shelter substrate and sufficient prey availability. The original mating pair persisted and reproduced through the 2025 season, indicating adequate adaptation to miniBIOTA's terrestrial conditions.
A first brood was noticed September 2, 2025, roughly four months after the mating pair was established. Multiple molted exoskeletons have been found since, indicating that second-generation individuals have survived initial instars and are progressing through molts. One juvenile was consumed by a Red House Spider, confirming both that juveniles dispersed from the mother and that they face predation in the closed system. As of March 2026, at least one individual was confirmed present in the Lowland Meadow; the population count of five is from the record and has not been confirmed by a recent census. The subsequent decline to approximately one individual (August 3, 2026) is confirmed to have been caused by the same predator: scorpions caught in Red House Spider webs and eaten.
Nocturnal apex invertebrate predator in the terrestrial food web of miniBIOTA. Preys on crickets, roaches, and small invertebrates, regulating prey populations in the Lowland Meadow, Mangrove Forest, and Lakeshore. The population is simultaneously a predator in its own right and a prey item for larger arachnids, particularly the Red House Spider.
