In year 2010, it was seen for the first time in the western part of country and it was identified by some routine observations. Is considered a non-native species knowing that originated in America.

Having in mind that larva is the most important stage, if we refer to damage plants, all our attention was directed to this. Somewhat, the results certify the polyphagism of this species, indicating numerous species of infested plants. Among, frequently infested with larval colonies, in green spaces, were Acer negundo, Acer pseudoplatanus, Ace
