– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: July Belle
ID pointers: Confusion species is the July Belle and sometimes the two species are indistinguishable. One of the best ID features is the shape and position of the discal spot – small and rounded in the July Belle (luridata) and “Tear Drop” shaped in the Lead Belle (mucronata) and more centrally positioned between the 2nd & 3rd Crosslines. Although this character is not always helpful, it is a good guider, along with flight period. The Zig Zag outermost crossline is also more well defined thann on July Belle. Generally the moth appears more brightly marked than July Belle.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
