I photographed a very young larva tentatively identified as Marmara sp. in a short, whitish, linear stem mine in late June. The larva's mine was later destroyed by an Ophiomyia sp. agromyzid larva mining the same stem (record 0034), and the gracillariid larva evidently did not survive the competition with the fly.
