A Technical Report from The Bartlett Tree Research Laboratories
The box tree caterpillar (Cydalima perspectalis) is a defoliating pest of box (Buxus) plants. Although a native to East Asia, adult moths were first recorded in the UK in 2008. By 2011 larvae were reported in private gardens in the counties of Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey and Sussex. By the end of 2014 the moth had become established in parts of London and surrounding counties. Where caterpillars are found, severe defoliation of box plants occurs.
