Backyard discovery rewrites biology: ants, wasps, and oaks reveal a hidden alliance
Eight-year-old Hugo Deans spotted BB-sized galls near an ant nest in his backyard, prompting researchers to test whether ants disperse galls the way they disperse seeds. Field and lab experiments showed ants are drawn to the galls' kapéllo caps, which carry fatty acids similar to seed elaiosomes, revealing a three-way interaction among oaks, cynipid wasps, and ants. The result suggests ants can transport galls, highlighting a nuanced signaling network in nature and potentially upending textbook views of plant–insect relationships and forest dynamics.
