The Common Green Capsid Bug is a sap-sucking insect belonging to the insect family of 'True Bugs'. A female will lay up to 200 eggs each fall, which then go on to hatch the following spring. Nymphs begin to feed on woody plants, but complete development feeding on herbaceous plants.


May damage ornamental, fruit and vegetable plants.


Adults: Vary in colour from green to red/ brown, around 6mm in length, winged and have a long, slender feeding tube and long wispy antennae. They are oval in shape, the legs long and stilt-like. The tip of the body where the wings can be seen are dark tinted. Nymphs: Young Capsid bugs are known as nymphs, they are similar in shape, and paler green colour to the adult, but are smaller and wingless. Eggs: Laid into cracks in tree bark, woody stems, and at the base of hedges.


Active late spring to autumn. Capsid bugs feed on plant sap at the shoot tips or flower buds. They insert their mouthpiece into the plant material, on doing so release toxic saliva and so cause deformation of plant material as it develops. Young leaves develop distorted in shape, possibly with small brown edged holes, that may die off completely. Flower buds may develop distorted and the flower may be lopsided or may fail.












Biological treatment

Most plants can cope with Capsid bug attack, but it may look unsightly. Affected leaves can be removed with care and disposed of safely. Removal of plant debris in autumn, winter months and dispose of safely. Will remove over-wintering sites for some Capsid bugs. Growing young vegetable plants under fine insect resistant mess may give some protection.
