Identification TipsLook for its uniformly pure white coloration and delicate build. While faint crosslines can be present, the overall lack of prominent markings and discal spots helps distinguish it from similar white geometrid moths.
Description
A small, delicate moth with entirely pure white, somewhat translucent wings and a slender white body. Very faint, wavy greyish crosslines may be present on the wings.
