The green immigrant leaf weevil is a small, brilliant metallic green weevil covered in tiny round scales, with pale antennae ending in a dark club. The scales can wear away with age to reveal the darker body beneath.
Adults feed on the young leaves and blossom of trees such as hazel, oak and fruit trees through spring and summer, while the soil dwelling larvae feed on roots and take about a year to develop.
