How long is flies memory?

Research suggests that fruit flies (Drosophila melanogaster) have a memory span ranging from a few minutes to several hours, depending on the type of learning and the specific conditions. They can retain associative memories, such as linking a certain smell with a positive or negative experience, for up to a few days. However, their short-term memory is more transient and typically lasts for about 5 to 20 minutes. Overall, flies exhibit impressive memory capabilities despite their small brains.
