Drosophila immigrans
Drosophila immigrans is a vinegar fly in the family Drosophilidae, belonging to the Immigrans-tripunctata radiation within the subgenus Drosophila. It has been used in evolutionary studies to understand virus-host coevolution. The species exhibits seasonal migration patterns in response to temperature extremes and shows altitudinal variation in body melanization correlated with fitness traits. It has a close ecological association with Penicillium moulds on citrus fruit.
