ypsena

Ypsena is a genus of moths in the family Geometridae. The genus was first described by William Warren in 1896. Ypsena moths are found in Asia. Species within this genus are characterized by their wing patterns and often exhibit cryptic coloration, aiding in camouflage against bark or foliage. The larval stage, or caterpillar, of Ypsena moths feeds on various plant species, with specific host plants varying depending on the particular species. Information on the life cycle and detailed ecological roles of many Ypsena species is still an area of ongoing research. Taxonomic classification within the Geometridae family places Ypsena based on morphological characteristics of both the adult moths and their immature stages. Further research aims to clarify phylogenetic relationships within the genus and its position within the broader moth families.
