Metallus albipes
The larva of the sawfly Metallus albipes mines the leaves of Raspberry, producing a large, almost full depth blotch with scattered frass. The mine is identical to that of M. pumilus, but the larva is different so it can be identified to species if the larva is present.
The mine of Metallus pumilus is similar but the larva of this species has three ventral spots, whereas M.albipes has two (as shown).
Adult: Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters.
Leafmine: Records of the leafmine must include a backlit images of the mine to show the frass, and also dorsal and ventral views of the larva. Please state the host plant when submitting a leafmine record.
Anywhere that Raspberry plants occur. Found on wild and cultivated Raspberry, preferring shaded situations.
Larval mine can be seen when Raspberry is in leaf, usually in early autumn.
True status in Britain is difficult to determine due to lack of records, but it would appear to be fairly widespread in England.
Status in Leicestershire and Rutland not known.
