Phytomyza actaeae: young mine on Actaea spicata

young mine and feeding punctures


Large upper-surface, greyish-green, later brownish, blotch with conspicuous primary and secondary feeding lines. Often several larvae in a mine. Frass in irregularly dispersed granules. According to Hering (1957a), pupation takes place outside the mine, but Pakalniškis (2004a) states the opposite.


Ranunculaceae, oligophagous

Actaea europaea, japonica, spicata.

Dreger & Myssura (2005a) additionally mention Clematis.


Mines from May to August (Hering, 1957a).


The picture above illustrates the first observation on the Benelux.

distribution within Europe

From Scandinavia to the Pyrenees, Alps, and Poland (Fauna Europaea, 2008); also Slovenia (Maček, 1999a).


Mandibles with 2 alternating teeth; front spiraculum bifid, with ca. 12 papillae; rear spiraculum with 16-18 papillae (de Meijere, 1937a).


Phytomyza nigrociliata Sasakawa, 1961.


Also Beri (1971e) published a description of the larva. However, the hostplant he mentions, Aster asperulus, makes it clear that his identification is incorrect.
