Description/
Field Marks: |
Basal two thirds of forewing light brown to brown with dark brown spots. Apical third dark brown with a broken light brown line in the middle. Hindwings grey-brown, with like-colored fringe getting progressively lighter towards the anal veins. |
| Similar Species: |
- Very similar to P. gossypiella and can only be separated by genitalia. See P. gossypiella genitalia here P. gossypiella larvae can be differentiated from P. scutigera by the crotchets on the abdominal prolegs, which are arranged in two transverse bands, and the anal crotchets as being divided into two groups.
- Pinned specimens of related species. (Hint: select View by Region on the related species page.)
