A rather rare species throughout Belgium.
Native
Three Belgian species Yponomeuta live on the host plant Euonymus.
Caterpillars of Yponomeuta cagnagella and Yponomeuta irrorella are very difficult to distinguish.
In contrast to the caterpillars of Y. cagnagella which live socially in a web, Y. irrorella caterpillars live individually in a web.
The caterpillars of the third species Yponomeuta plumbella are easy to distinguish from the other 2 species.
