Trioza rotundata Flor, 1861
larva (from Conci & Tamanini, 1987a)
larvae in shallow pits at underside of the leaves; at the other side a low dimple. Larvae flat, almost circular, surrounded by a circle of radiating wax threads. Young larvae are light ochreous in colour, older are darker, and then very hygrophilous. Univoltine, hibernation as imago in conifers.
Conci & Tamanini (1987a) suppose that under normal circumstances Cardamine species are the actual host plants.
