Feature(s) |
Close examination of the larvas mouthpart is one way to distinquish the two species. The chewing part or mandibles can be seen above. The mandibles can be removed. Upon closer examination the presence or absence of a mandibular process or retinaculum can be determined. A hand lens or dissecting microscope will be need for this process. |
