Ant‑eating spiders commonly refers to Zodariidae and related ant‑specialists showing a strong preference for ant prey. Some ant‑mimicking jumping spiders (e.g., Myrmarachne) are famed for mimicry, though not all are ant specialists.
Ecology & Biology
Prey/tactics: typically worker ants; spiders use sidestep ambush and stab‑and‑retreat to avoid mandibles/stings.
Mimicry: chemical camouflage via cuticular hydrocarbon acquisition/mimicry; foreleg waves imitate “antennae”.
Life history: mostly ground‑dwelling; webs/nests in litter, under stones or crevices; females frequently guard egg sacs.
Identification
Size: commonly ~2–12 mm body length; long, slender legs for cursorial running.
Colour: brown to black; some species with a distinct ant‑like gestalt.
Eyes: eight eyes; male palps often diagnostic in Zodariidae.
Range & Habitat
Widespread across tropical–temperate regions, frequent in leaf litter, grasses, sandy soils and beneath stones—often near ant trails/nests.
Conservation & People
Role: natural ant predators structuring ground food webs.
Safety: generally shy and medically insignificant to humans.
IUCN: group overview; most species unassessed. Marked Not Evaluated (NE) here.
