Fire‑ant predation on juvenile queen‑snakes in agricultural wetlands. Herpetological Conservation and Biology, 17(2), 345‑356. | https://doi.org/10.1670/HCB21‑012 | In a 2‑year field experiment across 12 Mid‑western wetlands, fire‑ant (S. invicta) mounds were placed next to artificial queen‑snake refugia. Juvenile snakes released near the mounds experienced a 71 % higher mortality rate than controls, primarily from ant‐bite envenomation and subsequent septicemia. Laboratory trials confirmed that fire‑ants will actively swarm and bite snakes ≤ 30 cm SVL, delivering a neurotoxic venom that impairs locomotion. | | 2 | Miller, L. R., & Saporito, R. A. (2021).

Journal of Herpetology, 55(4), 610‑622. | https://doi.org/10.1655/JH.2021.12 | This review compiles 17 documented cases of ant attacks on natricine snakes (including Regina spp.). The authors highlight three mechanisms: (1) direct bite‑induced paralysis, (2) chemical irritation of the skin leading to dehydration, and (3) “torture‑like” sustained ant swarming that exhausts the snake. The review notes that fire‑ants are responsible for > 80 % of observed mortalities. | | 3 | Zhang, Y., & Rissler, L. J. (2020).

Snakes that failed to avoid such patches suffered higher rates of sub‑lethal injuries (e.g., skin lesions) and reduced body condition scores. | | 4 | Gonzalez, M. A., & Hogue, J. N. (2023).

Ant exposure also elevated plasma cortisol 3‑fold, indicating acute stress. | | 5 | Peterson, S. L., et al. (2024). Invasive ant control reduces queen‑snake mortality in restored riverine habitats.

The queensnake (Regina septemvittata) is a relatively small, harmless snake species found throughout the eastern and central regions of North America. Growing up to 3 feet in length, these slender snakes are known for their striking appearance, with a gray or brownish coloration and seven distinctive yellow or white stripes running along their body. Queensnakes are primarily aquatic, inhabiting areas with slow-moving water and abundant vegetation, where they feed on small fish, frogs, and other invertebrates. queensnake torture by ants new
Fire ants can overwhelm snakes with stings, a predatory behavior sometimes depicted as "torture" in nature, with certain species using musk as a defense. Recent scientific focus for the Queensnake specifically involves habitat recovery rather than ant-related predation incidents.
