Anisomorpha buprestoides
Added as a mating pair to the Lowland Meadow in November 2025, this walkingstick became the first of its species to survive past day one in miniBIOTA; the female appeared to lay eggs in the soil before dying on November 9.

Anisomorpha buprestoides is the Southern Two-Striped Walkingstick, a Florida-native phasmid (stick insect) found throughout the state in forest edges, shrub habitats, scrubland, and vegetated disturbed areas. It is one of only a handful of stick insects in the world capable of chemical defense: glands on the metanotum can spray anisomorphal, a potent terpene compound, as a mist with considerable accuracy. Direct spray contact with the eyes can cause severe irritation and temporary corneal damage in humans and other mammals; the species is handled with care by those familiar with it.
Sexual dimorphism is extreme. Adult females are large (7-8 cm), slow-moving, and cryptically colored in brown, tan, or orange with two pale cream lateral stripes. Males are much smaller (3-4 cm), faster, and often ride on the female's back for extended periods, a behavior called mate-guarding. A "mating pair" in miniBIOTA observations likely refers to a female with a small male mounted on her back.
Anisomorpha buprestoides is a herbivore. In Florida habitats, it feeds primarily on oak leaves (Quercus spp.) and other broad-leaved plants. In miniBIOTA's Lowland Meadow, available food includes paspalum grass, creeping beggarweed, and other meadow vegetation; plant tissue and leaves at accessible height are the most likely dietary targets.
Reproduction is entirely female-driven: after mating, females scatter individual oval eggs one at a time onto the ground as they walk. The eggs closely resemble plant seeds and are dropped passively rather than placed. Eggs are hard-coated and can persist in the substrate for two to four months before hatching into small green nymphs. In Florida's warm climate, multiple generations per year are possible.
In the Lowland Meadow, the Southern Two-Striped Walkingstick is a foliage herbivore: it feeds directly on living plant tissue and converts it into insect biomass. Because it is large relative to other meadow insects (the female can reach 7-8 cm), each individual represents a meaningful transfer of plant energy into animal form. It also functions as potential prey for the terrestrial predator guild, scorpions, spiders, and opportunistic cockroaches all share the Lowland Meadow and would be capable of taking walkingstick nymphs.
The chemical defense spray means the walkingstick is not trivially predated. A spray interaction with another terrestrial species in miniBIOTA has not been documented.
The potential presence of eggs in the Lowland Meadow substrate after the November 2025 female's death represents an open question: if eggs were deposited, they may hatch into nymphs that establish a second generation without a fresh introduction.
Introduction context: The Southern Two-Striped Walkingstick has been introduced to miniBIOTA multiple times. The species records date_first_introduced as October 8, 2025. All prior introductions, including the October 2025 attempt, failed on the first day, the November 5, 2025 observation explicitly describes the mating pair surviving overnight as "the first time this species has made it past the first day in miniBIOTA." the record identity notes use the phrase "second-chance record" to describe the species' entry into the structured database after these repeated early failures. Introduction method and source are null; the individuals were likely collected locally.
Multiple prior introductions failed on day one before the November 4, 2025 mating pair introduction. The pair survived past day one for the first time on November 5, 2025. One individual (likely the female) found dead November 9 after apparent egg-laying. Male fate unresolved. No hatchling record exists. Current population status Uncertain.
Primary Consumer and foliage herbivore. Feeds directly on living plant tissue using mandibles suited to leaf consumption. In Florida habitats, Anisomorpha buprestoides feeds primarily on oak and other broad-leaved plants. In miniBIOTA's Lowland Meadow, the most available plant material includes paspalum grass, creeping beggarweed, and other meadow vegetation. No specific feeding event was observed in a dedicated miniBIOTA record; herbivore role is based on species biology.
Florida-native terrestrial phasmid; adapted to the warm, humid conditions of peninsular Florida forests and scrub habitats. Tolerates the Lowland Meadow's day-night temperature cycle and ambient humidity. Specific tolerance measurements have not been taken in miniBIOTA.
Female found dead November 9, 2025; observer noted apparent egg-laying activity prior to death. Whether viable eggs were deposited in the Lowland Meadow substrate and whether any nymphs have hatched is unresolved.
