Flybase is free to use but not free to make. It takes large teams of people and millions of dollars a year to create the knowledgebas and tools for fly research. Please donate generously.

FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...
