Common names: Box tree moth [En], Pyrale du buis [Fr], Buxusmot [Nl], Buchsbaumzünsler [De], Piralide del bosso [It]

Invasive species

Meise, BRABANT ● Belgium

Description: The wingspan of the adult form is 40–45 mm. Two variants are observed, the most common one is mostly white while the other is most entirely light brown.
First larvae just coming out from the egg are about 1–2 mm long. Larvae development brings them in four weeks to about 35–40 mm at maximum. There is some shrinkage at the beginning of the nymphosis, pupae are 25–30 mm long, first green with browning longitudinal lines, then more and more brownish.

Biology: There are two or three generations per year with adults on the wing from April/May to September.
The larvae feed on the leaves and shoots of Buxus species.
The species overwinters as a juvenile cocooned larva (about 5–10 mm long), protected in an hibernarium made of two leaving buxus leaves solidly joined by silk.

Distribution: It is native to eastern Asia (Japan, China, Taiwan, Korea, the Russian Far East and India).
It is an introduced species in Europe, first recorded in Germany in 2006, and subsequently in Switzerland and the Netherlands in 2007, Great Britain in 2008, France and Austria in 2009, Hungary in 2011, Romania and Turkey. It is also known from Slovakia, Belgium, Croatia, Italy, and Denmark.
