Pumpkin Gall Wasp
Dryocosmus minusculus
The Pumpkin Gall Wasp is a tiny insect that makes little round bumps, called galls, on oak leaves. These galls look like small pumpkins and are home to the wasp's babies!
Habitat: Forests
Appearance
The Pumpkin Gall Wasp is a tiny, dark-bodied insect, typically black or dark brown, with a shiny exoskeleton and yellowish-brown legs. It has a rounded abdomen and short antennae, differentiating it by its minute size and often obscure presence without its distinctive gall.

Interesting facts
Many Pumpkin Gall Wasps are all female; males are super rare or not found at all!
Some galls can look exactly like miniature pumpkins, even turning orange when mature!
Sometimes, other insects called 'inquilines' sneak into the gall to share its shelter!
The adult wasp that makes the gall is many times smaller than the 'pumpkin' it creates.
Special abilities
Ability
