Ophiomyia beckeri (Hendel, 1923)
Lapsana communis, Nieuwendam
In Asteraceae the larva mostly lives as a borer in the midrib of the leaves. From there short corridors are made into the blade. Also a corridor can be made overlying the midrib. In Euphorbia a small mine is made in the bracts of the inflorescence. The final mine strongly resembles the one of Liriomyza strigata, but the branches are virtually free from frass; this is accumulated in the resting place of the larva, in the base of the midrib. There also pupation takes place.

Also mentioned from Centranthus by Robbins (1991a).
The occurrence on Euphorbia does not match well with the long list of Asteraceae host. Spencer (1966c) therefore supposed that Hendel had made a mistake while describing his single specimen of M. euphorbiae, and that Euphorbia gerardiana (now seguieriana) was not the actual host plant. Martinez & Sobhian (2000a) later agreed with this conclusion. However, Spencer’s supposition is not simply in accordance with other references to M. euphorbiae on Euphorbia serrata (by Hering), E. amygdaloides (Kvičala), E. spec. (Skala & Zavřel) and E. helioscopia (Maček).
Larvae in May-June (Hering, 1957a).

NE observed (Ellis, various localities).
LUX not recorded (Fauna Europaea, 2008).
