Capsid bug

Symptoms Damage on leaves and buds start to appear from late May to September. The leaves near the shoot tips have many small, brown-edged holes, and flower buds may fail to develop or open unevenly. Capsid bugs suck sap, and as they feed they secrete a toxic saliva into the plants which kills cells immediately around the feeding area. Spot them The adults are 6mm long and have distinctive wings. When the wings are folded over, the transparent part of the wings shows as a clear diamond area at the rear of the insect.
