On Hazel I found a couple nfy (new for year),. so that's both the Phyllonorycter mine species on this tree sorted for 2022!
A single first cycle Phyllonorycter nicellii, the Phyllonorycter found on the underside of Hazel leaves, was spotted on the main circuit, near the dead Ash trees. Hardly any other Hazel was actually checked. As usual you see the nibbled windows around the edge of the mine from the upperside, together with the pulled up ridge, and then the silvered lower epidermis from the underside. The common name is the Red Hazel Midget.
And close by there was a single Phyllonorycter coryli, the larva of the nut leaf blister moth, with the silvered upper epidermis visible in the highly distorted valley of the puckered up leaf.
