Hello,

upper side of the leaf:
www.galerie-insecte.org/galerie/image/dos181/big/5db26798.jpg
Pierre Duhem : France : Saint-Leu-la-Forêt : 95320 : 27/04/2017
Altitude : 183 m - Taille : Sans objet
Réf. : 181769

lower side of the leaf:
www.galerie-insecte.org/galerie/image/dos181/big/5db26801.jpg
Pierre Duhem : France : Saint-Leu-la-Forêt : 95320 : 27/04/2017
Altitude : 183 m - Taille : Sans objet
Réf. : 181770

I tried to pinpoint the author of this mine, on http://www.bladmineerders.nl and http://www.leafmines.co.uk, but without success.

I'm now thinking about a mine caused by a Coleophoridae, whose case fell from the leaf for whatever reason, leaving this result. I visited the same site yesterday and found several other leaves with similar pattern.

Thanks in advance for any clues.

forinstance: http://agrozoo.ne...bddc255953

You have tentiform mine between two side veins. Holes are exit slits.

bladmineerders.nl: Lower-surface, little contracted tentiform mine. Often several mines in a leaf. Frass concentrated in a corner of the mine, from above recognisable as a black patch

In order to locate frass & larva & identify anything allways do backlight photo such as this (central image): http://agrozoo.ne...40cf78da60
You can see that top photo is practicaly useless.

These certainly look like typical Coleophora feeding signs to me.
