Rob
Edmunds and John Langmaid found examples of Emmetia type
mines on Bramble (Rubus fruticosus) at several sites in
shady sitautions in both Hampshire and Surrey in the Summer
(2005).
They
differed from the typical autumn generation mines of
E.marginea as they formed large, flat mines, which could
extend from the mid region of the leaf to the edge. The
Summer generation mines in sunny sites were the typical
compact E.marginea type.
Some
mines were at the edge of the leaf and caused it to curl
over.
An
example of one of the broad flat mines is illustrated
opposite.
