A Beltian body
is a structure found on the leaves of some species of Acacia
. Beltian bodies, named after Thomas Belt
, are found on the tips of each leaflet and are rich in lipids and proteins and often red in colour. They are believed to have evolved in a symbiotic relationship with ants. The ants live inside special plant structures (Domatia
) or near the plant and keep away herbivores
. Other ant-mutualism related plant structures include Beccarian, Mullerian and pearl bodies.
