The leafhoppers are a family (Cicadellidae) of

Sap is a fluid that circulates through a plant's vascular system, in a similar way to blood moving through our veins. Phloem sap carries the sugars produced in the leaves by photosynthesis down to roots and other storage organs, as well as carrying minerals and hormones. Xylem sap is watery and transports nutrients absorbed by the roots upwards to the rest of the plant. Some plants leak sap from wounds or pruning cuts, and this is known as bleeding.

Rose leafhopper can be considered part of the biodiversity roses in gardens support; although the mottling can be very noticeable roses are often able to withstand large leafhopper populations.

• Tolerate the mottling caused by rose leafhopper it often has no effect on plant vigour or flowering
• Encourage predators and other natural enemies of leafhoppers, in the garden, such as birds, ladybirds, wasps and ground beetles

The pale yellow adult rose leafhoppers are 3.5-4 mm long and sit with their wings folded back over their bodies. When disturbed, the adults readily jump and fly short distances. The leafhoppers overwinter as eggs inserted in the leaves and young shoots which hatch in May. The creamy white immature stages, known as nymphs, then begin to feed on the lower leaf surface. They reach the adult stage in July and lay eggs which hatch to produce a second generation. Overwintering eggs are laid in the autumn but in mild areas the adults may live until late winter.
