The larvae were found on the leaves of  Rhododendron mollesubsp.  japonicumplanted in a park. They occurred in late June and the adults emerged next spring indoors, which strongly suggests that the species has a univoltine life cycle. The larva (probably in middle to late instars, Figs 1–3) is a solitary external feeder, often assuming a coiled resting position, common in tenthredinid sawflies ( Fig. 3). In the late instar ( Figs 2–3), the head is light brown with a black ocularium. The trunk is pale gray with slight purplish tinge. The anterior margin of the prothorax, broad lateral ventral parts (the postspiracular lobes and below) throughout the trunk, and most of the eighth and tenth abdominal segments are creamy white.
