Agromyza ferruginosa van der Wulp, 1971 
Symphytum officinale, Nieuwkerk NB
Symphytum officinale, Amstelveen, Schinkelbos: oviposition
mine
A dozen eggs are deposited in a semicircle at the leaf underside. After hatching the larvae eat themselves a communual corridor. After the first moult they begin the making of a very large, dark brown communal blotch, with conspicuous secondary feeding lines.
hostplants
Boraginaceae, oligophagous
Pulmonaria officinalis; Symphytum asperum, officinale.
phenology
Larvae between May and November in two generations (Hering, 1957a).
BENELUX
BE recorded (Scheirs, De Bruyn & von Tschirnhaus, 1996a).
NE recorded (van der Wulp, 1871a).
LUX not recorded (Fauna Europaea, 2007).
distribution within Europe
From the UK to Italy, and from Lithuania to France (Fauna Europaea, 2007).
larva
notes
The mines can be difficult to distinguish from those of the much more common A. abiens. In that species the eggs are deposited singly, albeit often several in a single leaf. The young larvae start by making a narrow corridor; after their first moult the begin making a blotch. Even though these blotches generally fuse to a common megablotch, mostly it is possible to recognise remnants of the individual initial corridors as the hallmark of abiens.
Described by van der Wulp from the Netherlands (dunes of the Hague and Rotterdam).
