detail of the same mine, lighted from behind
Very shallow, irregularly branched corridor, sometimes a narrow blotch. The mine is upper-surface, sometimes also interparenchymatous. The colour is pale green, larer more rust-xcoloured. Frass in small, widely spaced grains. Papation takes place within the mine. Hibernation in the mine, among fallen leaves.
Malus “domestica”, sylvestris.
The occurrence on pear, as shown above, must be interpreted as a rare case of xenophagy, where an egg has been deposited on a foreign host plant. Be it that in this case the “wrong” host is very closely related to the “correct” one.
Larvae in May-June and August-October (Hering,1957a).
BE recorded (Chris Snyers, 2011).
