Hentz Striped Scorpion

The Hentz Striped Scorpion is the top nocturnal invertebrate predator in miniBIOTA's terrestrial biomes, hunting crickets, roaches, and small invertebrates after dark while sheltering beneath bark and leaf litter by day. Two individuals introduced in 2025 turned out to be a mating pair; a first brood was confirmed by September 2025, and the population now counts five individuals. One juvenile was consumed by a Red House Spider, and multiple molted exoskeletons have been found, indicating that second-generation individuals are growing.

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 and Mangrove Forest and moves prey biomass into a long-lived, slow-reproducing predator layer.

At five individuals in a closed terrestrial system, the population is Vulnerable. Second-generation individuals add resilience but also face predation from the Red House Spider, which has already consumed at least one juvenile. The balance between juvenile survival and attrition will determine whether the population can sustain itself without intervention.

Both founding individuals were introduced in 2025. All early events (introduction, brood, early molts, spider predation) are referenced in the species record; no dedicated observation records exist for those events.

May 5, 2025: First individual introduced.

July 2, 2025 (on record): Second individual introduced. These two turned out to be a mating pair.

September 2, 2025 (on record): First brood noticed; this is the first observed brood on record.

Early period: The species record documents "recovery and relocation events, feeding activity, confirmed second-generation appearance, molts, and predation on a young scorpion by a Red House Spider." No dedicated observation records exist for these events. Multiple molted exoskeletons were found, indicating that second-generation individuals survived beyond birth and are progressing through instars.

March 26, 2026: The species was observed for the first time after a long period without sightings, confirming it is still present in the Lowland Meadow. The note mentions the last confirmed count was two individuals, with current population uncertain. Video evidence.
