- Leafhoppers that occur on apple in the UK are small (mostly 3-5 mm long) slender insects, usually green or yellow in colour (though some species are brightly coloured), found mainly on the undersides of leaves associated with the speckling damage they cause to foliage.
- They are active insects and jump and fly readily especially in warm conditions.
- The various species that occur on fruit trees are generally similar in appearance though some have characteristic markings on their body or wings.
Adult
The commonest species are 3-4 mm long, pale yellow with a yellow abdomen.
