| Family | Agromyzidae[M,P,A] |
| Lower taxon | cf. Ophiomyia sp. |
| No. spp. involved | One confirmed [1-C] |

In the current study, puparia of this agromyzid were located in dead stems of the host during the dormant season. The location of the puparium just under the epidermis of the stem suggests that the larva feeds shallowly as a subepidermal stem miner and does not penetrate into deeper tissues. A single female adult was reared in spring 2022. The insect appears to belong to the genus Ophiomyia.
