| Similar Species: |
- Genitalic dissection can be used to distinguish L. glycinivorella from similar looking Cydia. Male L. glycinivorella possess paired scent organs on the 8th sternite (Characteristic of Leguminivora see Horak (2006)) in a pocket that consist of many short black scales not longer than the 8th segment. (see genitalia plate where one scent organ has been removed and one is exposed)
