Cydalima perspectalis or the box tree moth is a species of moth of the family Crambidae, first described by Francis Walker, the English entomologist, in 1859. Native to Japan, China, Taiwan, Korea, far-east Russia and India, it has invaded Europe; first recorded in Germany in 2006, then Switzerland and the Netherlands in 2007, Great Britain in 2008, France and Austria in 2009, Hungary in 2011, then Romania, Spain and Turkey. It has been seen in Slovakia, Belgium and Croatia. Eggs are 1 mm in diameter, located under green unattacked leaves. 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. 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. (Source: Wikipedia.org, CC BY-SA)
