Pyknometrillas

Pyknometrillas is a genus of moths in the family Geometridae. The genus was described by Louis-Auguste de Prött in 1931. Moths in this genus are typically small to medium-sized, with wingspans ranging from approximately 15 to 25 millimeters. Their coloration and patterns are often cryptic, providing camouflage against bark or foliage. The forewings and hindwings generally share similar markings, though the forewings are usually more prominent.

The larvae of Pyknometrillas species are believed to be herbivorous, feeding on the leaves of various plants. Specific host plants can vary depending on the geographical distribution of the moth. Adult moths are generally nocturnal and are attracted to light. They are found in a range of habitats, including forests and woodlands. The geographical distribution of Pyknometrillas is primarily within the Palearctic region. Further research is ongoing to fully understand the life cycle, behavior, and ecological roles of these moths. The exact number of species within the genus and their detailed descriptions are subject to ongoing scientific classification and revision.
