Phytomyza heringiana: mine on Pyrus communis - xenophagy

detail of the same mine, lighted from behind

mine

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.

hostplants

Rosaceae, monophagous

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.

phenology

Larvae in May-June and August-October (Hering,1957a).

BENELUX

BE recorded (Chris Snyers, 2011).

NE recorded (Houtman, 1952a).

LUX not recorded (Fauna Europaea, 2008).

distribution within Europe

From Lithuania to the Pyrenees, and from the UK to Italy (Fauna Europaea, 2008).

larva

De Meijere (1926a), Viggiani (1962a).

notes

Mainly in cultivated apples, but not causing any damage worth mentioning (van Frankenhuyzen & Freriks, 1971a).
