Korsformiga

Korsformiga is a fictional species of ant commonly used in educational materials to illustrate principles of ant biology and morphology. The name combines kors, meaning cross in several Scandinavian languages, with formiga, the word for ant in Portuguese and Spanish, chosen for a distinctive cross-like feature described in the fictional literature.

Taxonomy and naming in the educational scenario place Korsformiga in the family Formicidae, often treated as a monotypic or small, imagined lineage within classroom resources. In the standard fictional account, workers range about 3–4 millimeters in length and show color variation from light chestnut to dark brown. A distinctive cross-shaped pattern of sculpturing on the mesosoma is cited as the key diagnostic trait, giving rise to the common name.

Distribution and habitat are described within a made-up ecosystem, with Korsformiga portrayed as endemic to temperate forest regions of a fictional continent. Nests are subterranean or located in rotting wood, and colonies are headed by a single queen, with a workforce of sterile workers and occasional soldiers.

Behavior and ecology follow typical ant patterns: caste differentiation, cooperative brood care, and social foraging guided by pheromones. Reproduction occurs through nuptial flights in the fictional setting, followed by colony budding. Diet is omnivorous, including small invertebrates, nectar, and honeydew. In educational contexts, Korsformiga serves as a neutral example to discuss morphology, social structure, and ecological interactions without attributing it to a real species.
