Tarus

Tarus refers to a genus of moths in the family Geometridae. These moths are commonly known as geometer moths or spanworms. The genus Tarus is characterized by specific morphological features, including wing venation and genitalia, which distinguish it from other genera within the Geometridae family. The larvae of Tarus moths, like other geometer moths, exhibit a peculiar method of locomotion by extending their bodies and then bringing their hind legs forward, creating a looping or "measuring" motion, hence the name "spanworm" or "inchworm."

The distribution of Tarus species is primarily found in Palearctic regions. Their life cycle typically involves an egg stage, a larval stage (caterpillar), a pupal stage, and an adult stage. The caterpillars are often cryptically colored and feed on the foliage of various plants, with specific host plant preferences varying among different species. Adult moths are generally nocturnal and are often attracted to light sources. Their wingspan and coloration can vary, but they typically possess a slender body and broad wings. The study of Tarus moths contributes to the broader understanding of insect biodiversity and ecological interactions within their native habitats. Further taxonomic research continues to refine the classification and relationships within the Geometridae family, including the genus Tarus.
