Urophora cardui
The Thistle Stem Gall Fly is a tiny insect that makes special bumps called galls on thistle plants. These galls are like cozy homes for the fly's babies to grow in!
Hábitat: Grasslands
The Thistle Stem Gall Fly is a small fly with a dark, robust body, often appearing brownish-black. Its most distinctive feature is its wings, which are patterned with dark bands and clear spots, giving them a mottled, checkered look. This wing pattern helps distinguish it from other small flies.
