Creature
Gall wasp
Invertebrate
A tiny wasp that causes oak trees to grow strange, round structures called galls.
💡 Fun Facts
- The female wasp lays an egg inside an oak leaf bud, tricking the tree into growing a protective 'gall' around it.
- The developing wasp larva lives safely inside the gall, eating the nutritious tissue.
- There are hundreds of species of gall wasps, each creating a uniquely shaped gall on the tree.
