Rose galls

Rose leafhopper creates pale blotches and fine white mottling on the upper leaf surfaces, with evidence of white nymphs and adults visible on the undersides. The creamy-white to light yellow insects are about 3mm long; when disturbed, they readily jump and fly. Cast skins accumulate on leaf undersides.

Damage is mainly aesthetic; severe infestations in dry summers can cause leaf drop. Fall egg-laying wounds canes, creating fungal entry points. Monitor for mottling in mid-summer and tolerate minor damage. For severe cases, strong water spray dislodges adults without chemicals needed.
