Look out for armyworms

Published: 19 June 2008

The exciting discovery of armyworms in the British Isles in July 2004 (see April 2005 Bulletin), and the subsequent discovery of a second site in 2006 (see December 2007 Bulletin), has led to a request for anyone walking in woodland in July to look out for mysterious marching columns of maggot-like larvae.

The larvae of Sciarid flies (dark-winged fungus gnats) are roughly 7mm long and tens of thousands of these tiny larvae form spectacular moving columns known as armyworms.

Anyone spotting these columns in the UK can report the find to the AES using our contact page.
