Centruroides hentzi

Hentz Striped Scorpion

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.

Overview

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 reached five individuals on record. One juvenile was consumed by a Red House Spider, and multiple molted exoskeletons have been found, indicating that second-generation individuals grew. As of August 3, 2026, the population is believed to have declined to approximately one individual, based on an incidental impression while assessing predation risk for a newly introduced Greenhouse Frog group rather than a dedicated census. The cause of that decline is confirmed: scorpions became caught in Red House Spider webs and were consumed. Josue holds video of this but has not yet reviewed it for exact dates or the number of individuals lost.

Natural History

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.

Ecological Role

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. Exact dates and the number of individuals lost this way are not yet documented; video evidence exists but has not been reviewed.

miniBIOTA Evidence

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.

August 3, 2026: Population believed to have declined to approximately one individual, noted incidentally while assessing predation risk ahead of a new Greenhouse Frog introduction to the Lakeshore. Not a dedicated census; cause of the apparent decline from five to approximately one is not established. Observation record, August 3, 2026.

August 3, 2026 (range documentation): Josue clarified that the species has long ranged into the Lakeshore biome, in addition to the previously documented Lowland Meadow and Mangrove Forest, surfaced while assessing predation risk for the newly introduced Greenhouse Frogs. This reflects a standing range rather than a new expansion on this date. Observation record, August 3, 2026.

August 3, 2026 (cause of decline confirmed): Josue confirmed the population decline from five to approximately one individual was caused by scorpions becoming caught in Red House Spider webs and being eaten. He has video of this but did not retrieve the exact date(s) or count in this session. Observation record, August 3, 2026.

Confirmed:

  • First individual introduced May 5, 2025; second July 2, 2025; confirmed mating pair
  • First brood September 2, 2025
  • Multiple molted exoskeletons found (second-generation individuals progressing through instars)
  • One juvenile confirmed consumed by Red House Spider
  • Species confirmed present in Lowland Meadow March 26, 2026; video evidence
  • Population listed at 5 individuals as of the most recent formal record
  • Population believed reduced to approximately 1 individual as of August 3, 2026 (incidental impression, not a census)
  • Long-standing range into the Lakeshore, in addition to Lowland Meadow and Mangrove Forest, documented for the first time August 3, 2026
  • Cause of the decline from five to approximately one individual confirmed as Red House Spider web predation, August 3, 2026

Inferred:

  • Ongoing nocturnal hunting of crickets, roaches, and small invertebrates in the terrestrial biomes
  • UV-detectable fluorescence useful for nighttime census

Unknown:

  • Current status and location of any surviving individuals
  • Exact date(s) and number of individuals lost to Red House Spider web predation; video exists but has not been reviewed
  • Whether additional broods have occurred since September 2025
  • Whether any of the second-generation individuals reached maturity
  • What the "recovery and relocation events" referenced on record involved
