Chromatomyia fuscula (Zetterstedt, 1838)

Diptera, Agromyzidae

mine

Whitish, upper-surface, descending corridor, about halfway the blade. Frass in distinct black grains that are lying further apart than their diameter. Pupation in the mine; front spiracula penetrate the plant epidermis.

hostplants

Poaceae, broadly polyfagous

Alopecurus pratensis; Arrhenatherum elatius; Avena sativa; Avenula pubescens; Bromopsis erectus; Dactylis glomerata; Glyceria nbotata; Holcus lantus; Hordeum vulgare; Ochlopoa annua; Phalaroides arundinacea; Phleum pratense; Poa trivialis; Schedonorus giganteus; Secale cereale, Triticum aestivum.

phenology

Larvae in April-September (Hering, 1957a).

BENELUX

BE not recorded (Fauna Europaea, 2007).

NE Mentioned as occurring in the Netherlands by Beuk (2002a), but without referencce, and probably in error.

LUX not recorded (Fauna Europaea, 2007).

distribution within Europe

From Scandinavia to the Pyrenees, Italy and Serbia, and from France to Poland (Fauna Europaea, 2007); also ; ook Turkey (Mart, Tursun & Civelek, 2005a).

larva

Front spiraculum with 18-20, rear spiraculum with 8 papillae; both are fist-shaped. (The rear spiraculum this isn’t dagger-shaped, like in Ch. milii).

puparium

The orange-brown puparium can easily be discriminated from that of Ch. nigra because the ventral surface has a broad dark length zone.

synonyms

Phytomyza fuscula; P. avenae de Meijere, 1926; Ph. brevicornis Hendel (1934); Ph. dura (Curran, 1934); Ph. obscurifrons (Strobl, 1910); Ph. subcutanea (Bjerkander, 1793).

notes

De Meijere (1926a) forgot to indicate an origin when describing his avenae. Only later (1934a) this was disclosed, and turned out the be not the Netherlnds, but Sweden. Perhaps this is the background of Beuk’s (2002a) inclusion of fuscula in the Dutch list. The species is not mentioned in de Meijere’s final checklist of Dutch Diptera of 1939a.

In Scandinavia a serious pest on Oat and Barley (Darvas & Andersen, 1996a; Darvas, Skuhravá & Andersen, 2000a).

Surprisingly, the species hibernates in the adult stage, and is active in that season (Andersen, 1991a; Hågvar & Greve 2004a).
