Butterfly Migration


Did you know that butterflies migrate? All around the world you could cross paths with them!

For studying their migratory routes, we need citizen scientists all over the world, to track movements, find breeding sites and report observations!

​Check the images, videos and tips that we provide on the app “ButterflyMigration”, or the website to learn more about how to identify and how to find the butterflies, the caterpillars and their favorite hostplants.

What can you do?


  • Report observations: Observe, photograph and report findings directly to us or through our app “butterfly migration” or through open projects in citizen science platforms.


  • Monitor a breeding site along the year: Find a good spot near your home where the butterfly breed and count them along time. Follow the instructions from the app or contact us to set a site!


  • Collect specimens: Butterflies, pupae, caterpillars and their hostplants are processed and studied in the lab. Contact us to get a collecting protocol.


Our aim is to build a monitoring network to study the migration patterns of butterflies and better understand this outstanding phenomenon.
