Liriomyza congesta: vacated mine on Trifolium pratense

a mine like this can easily be mistaken for one by Agromyza nana


Upper-surface, unbranched corridor, relatively broad from the start on, but only weakly widening subsequently. The fresh mine is bright green, but turns whitish, later brown, quickly. Frass in a wide green band in the centre of the corridor, with small black granules at either side. Pupation outside the mine.

In southern Europe a pest on broad beans (Dempewolf, 2004a).

Rob Edmunds reared the species from Trifolium ochroleucon.

Cited by Gil Ortiz (2009a) also from Euphorbia; xenophagy?


Larvae from June to October (Hering, 1957a).


BE recorded (De Bruyn & von Tschirnhaus, 1991a).

NE recorded (de Meijere, 1924a, 1939a).

LUX recorded (Ellis: Kautenbach, Dudelange, Flaxweiler).

parasitoids, predators

Chrysocharis orbicularis; Diglyphus minoeus; Zagrammosoma talitzkii.


For a long time, L. trifolii (Burgess, 1880) was considered the correct name for this species. Now it is know that trifolii is a different species, native of the New World. However, since 1980 this real, American, L. trifolii has become an introduced pest in the Netherlands in greenhouses, particularly in chrysanthemum cultivation (d’Aguilar & Martinez, 1979a; Dempewolf, 2004a; Minkenberg & van Lenteren, 1986a).
