Micro-moth field tips: Coleophora juncicolella. This tiny Coleophora makes a beautifully detailed and well disguised case. With a case of only 4mm in length, the only real chance of seeing it is to beat or sweep some heather. This should dislodge lots of small pieces of heather. I found this one by beating the heather into an upturned umbrella at Lindow Moss, Wilmslow on 15.4.15. After a minute or two of careful observation, a piece of the heather started to walk about! Alternatively, put the contents of the sweeping or beating into a clear container and wait for the Coleophora larvae to walk up the side of the container.
