Note.

Leaf-mining larvae of this species have been found from 26 plant species belonging to three taxonomically isolated plant families: Aristolochiaceae (Fig. 11 A – G View Figure 11 ), Ranunculaceae (Fig. 11 H – M View Figure 11 ) and Asteraceae (Fig. 11 N – T View Figure 11 ). The morphology of the adult beetle (Fig. 11 A, B, G – H, N – P View Figure 11 ) and its male genitalia (Fig. 11 C, D, J, K, P, Q View Figure 11 ) suggest that all these specimens belong to this species.

Leaf mine.

Upper-layer linear-blotch mine in young instars, and full-depth blotch mine in old instars occur on mature leaves (Fig. 11 E – G, L, M, R, S View Figure 11 ). Frass is thin thread-like, deposited along meandering larval trajectory in the mine. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground. The mining pattern is largely similar among leaves of the different plant species / families.
