Alder Mines:
A few leaf mines on Alder along Whitehall Brook, Mottram St. Andrew on 15th September 2017:
- Heliozela resplendella
- Bucculatrix cidarella
Note the emergence hole where the larva has vacated the mine is on the upperside of the leaf, whereas both
Stigmella species on alder vacate from the underside of the mine.
- Caloptilia elongella
The larva makes this silvery mine in the early instar. It then feeds inside a rolled leaf.
- Phyllonorycter rajella
Note the main central crease.
- Phyllonorycter froelichiella
No central crease. A long mine, often starting from the midrib and extending to the leaf edge
- Phyllonorycter froelichiella
There is often a reddish spot in the angle where the midrib meets the main vein.
- Phyllonorycter klemannella
No central crease and mine much shorter than
Phyllonorycter froelichiella. Larva white.
- Phyllonorycter stettinensis
On the upper surface of the leaf.
