Small bright green sap sucking insects that feed on the shoot tips of many plants including fuchsias, hydrangea and roses. Whilst feeding these bugs secreate a toxic saliva that kills surrounding plant cells. Later as the leaves develop form the damaged shoots these dead areas tear into many small holes.
Check over vulnerable roses during the growing season and pick off the affected tips. You may find that Provado Ultimate Bug Killer range of insecticides and Multirose Bug Killer may help with this problem.
