• 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.

• Eupithecia segregata

  Pug moth

  Eupithecia segregata is a small moth in the family Geometridae described by Pearsall in 1910. It is one of many 'pug' moths in the genus Eupithecia, recognized by their narrow wings and distinctive resting posture. The species shows considerable phenotypic variation and exhibits altitudinal variation in flight period timing.
