Species Account

Current status (CHF, 2011): NEW COUNTY RECORD - Leeds 2009. The communal larvae of this moth have been reported from various sites in the London area since 2006, mostly on imported oaks. In 2009, a larval nest was found on an imported oak in Leeds. Searches in 2010 failed to find any more at this site however another larval web was found at a site in Sheffield, again on an imported oak. This species is a quarantine pest and any suspected occurrence should be reported to the Forestry Commission, however it may already be well established in the south east so it is likely that we may hear more about it in years to come.
