Neocoenorrhinus pauxillus (Germar, 1824)
< back
galleries are formed into the leaf blade

 

Food Plant: On a variety of rosaceous shrubs, particularly Crataegus (Hawthorn) , Prunus spinosa (Blackthorn) and Mespilus germanica (Medlar).

Egg: at the bottom of the leaf blade, in the midrib, close to the attachment of the petiole.

Mine: May-June

Notes: After oviposition the female bites into the midrib which causes the leaf to fold downwards at about 90°. The leaves turn brown and fall to the ground. The larva mines the midrib and makes side galleries into the leaf blade (as shown). In Pyrus sp. the mines turn black (Carina van Steenwinkel pers.comm.). The larva pupates in the ground and emerges next spring. A pest of fruit trees in Europe, though not in Britain. Found from Durham southwards, but absent in Wales, Scotland and Ireland. Mine shown on Malus domestica

Data: 28.vi.2015, Mol, (Antwerpen), Belgium
