Ant-mimicking Sac Spider (Castianeira sp.) - Corinnidae


The Ant-Mimicking Sac Spider is belonging to the Castianeira genus within the Corinnidae family. These spiders are being notable for their incredible ability to mimic ants in both appearance and behavior. This mimicry is helping them evade predators and is even allowing them to infiltrate ant colonies to steal their young. Being fast runners by nature, these spiders are often being found on the ground, among leaf litter, or under rocks, similar to the habitats of ants. They are thriving in various environments, including prairies, forests, and shrubby areas. Here is one in Tehatta, West Bengal, India, on March 8, 2025.
