Nettle pouch gall midge

The nettle pouch gall midge is a tiny fly that you almost never see. What you can see is its little home: a shiny, bumpy pouch on a stinging nettle leaf. The midge makes the nettle grow this pouch, and its babies live safely inside.

How fast is it?
Fun facts
The pouches are 3 to 8 millimetres big and can be purple or pale green.
Each pouch has a narrow slit for a door, usually on the underside.
Often many pouches grow side by side, and sometimes they grow into each other.
When the babies are big enough, they leave the pouch and go into the soil to change into grown-ups.
Sometimes other midge babies sneak into the pouch too. Some are just guests, and some hunt the babies that live there.
