The species was first described by Augustus Radcliffe Grote in 1880, originally under the Tarache. It is currently classified in the genus Ponometia within the Acontiinae.

Identification

Ponometia sutrix can be distinguished from similar noctuid by its bird dropping mimicry pattern and, where examined, genitalia characteristics used in -level within the . The MONA (Moth Photographers Group) or Hodges number 9119 provides a standardized reference for identification in North American moth surveys. Separation from such as Ponometia semiflava and other Acontiinae requires examination of wing pattern details and, in many cases, dissection and comparison of male or female genitalia structures.

Appearance

As a bird dropping moth, Ponometia sutrix exhibits cryptic coloration and patterning that mimics the appearance of bird droppings. This typically involves mottled gray, white, and brown coloration with irregular markings. The wings are likely broad and somewhat flattened at rest, contributing to the bird dropping illusion. Specific morphological details for this are not well-documented in available sources.

Distribution

Recorded from North America. Specific range details within this region are not well-documented in available sources.

Similar Taxa

  • Ponometia semiflava in the same with similar bird dropping mimicry; requires genitalia examination or detailed wing pattern analysis for separation.
  • Other Acontia/Ponometia speciesMultiple in this group share bird dropping mimicry; accurate identification often requires examination of genitalia or reference to geographic distribution and subtle pattern differences.
