oenia
Oenia is a genus of moths in the family Geometridae. The genus was described by Jacob Hübner in 1821. Oenia moths are found in Europe and Asia. They are typically small to medium-sized moths with intricate wing patterns. The larvae of Oenia moths feed on various herbaceous plants. The genus is characterized by specific morphological features of the adults, particularly in the wing venation and genitalia, which distinguish them from other genera within the Geometridae family. Further research is ongoing to fully understand the phylogenetic relationships and ecological roles of Oenia species. Classification within the Geometridae family can be complex, and ongoing studies often refine the placement of genera like Oenia based on new genetic and morphological data. The exact distribution and life cycle details can vary among the different species within the Oenia genus.
