Pest identification
What's eating my scabrosa rugosa rose?
Aphids (Macrosiphum rosae)
Signs: Colonies on shoot tips and flower stalks in spring and early summer; less damaging than on modern hybrid teas due to the plant's vigour.
Control: Water jet or insecticidal soap spray; natural predators (ladybirds, hoverflies) typically keep populations in check on healthy rugosa.
Japanese beetle (Popillia japonica) — US
Signs: Large single blooms devoured, petals and leaf tissue skeletonised; adult beetles aggregating from late June through August.
Control: Morning hand-picking into soapy water; neem oil spray as feeding deterrent; avoid pheromone traps near planting.
Rose sawfly larvae
Signs: Scattered window-paned or fully stripped leaflets; larvae on leaf undersides, active late spring to early summer.
Control: Inspect and hand-pick; spinosad or pyrethrin spray on affected foliage if populations spread.

Scabrosa Rugosa Rose pests — FAQ
What is eating my scabrosa rugosa rose?
Scabrosa (Rosa rugosa 'Scabrosa') is exceptionally disease-resistant with formidable thorns that deter large browsers. Aphids on tender new growth and Japanese beetles (US) attacking the large blooms are the main threats. Sawfly larvae can cause minor skeletonising. Its rugosa constitution makes it one of the pest-resistant outdoor roses available.
