Daytime mines challenge

Mine hunting is an easy way to do some mothing now that the summer is over. Please can everyone check their local St John's Worts for the mines of Ectoedemia septembrella.  They should be found throughout the county, but we've got very few records.  They are very distinctive indeed - with a thin line leading to a big round blotch in which the frass (dark droppings) form a spiral.  There are no other moth/fly mines on St John's Wort.  Please let me know if/where you find them.
