Hello.
This Chloropidae of 2.5 mm was observed yesterday on Choisya ternata at home (north of Yonne department, France). Calamoncosis may be the good genus. Are you in agreement with this suggestion ?
All my thanks.

Chloropidae, Oscinellinae, as already identified for Jean-Michel, this is Calamoncosis spec. to which belong robust species, mostly with sparcely punctured frons and ocellar triangle, a fine keel separating the two halfs of the face (space for the antennae), a gena which does not protrude before the anterior eye margin and a rugose scutum. Other important details for species identification cannot be seen in these images, except that the halteres are black. Calamoncosis spp. develop in grasses, being mostly host specific (e.g. Phragmites, Glyceria, Stipa), but flies had also been reared from dicots by M.v.T.

Hi,
I thought
Calamoncosis have all tarsae yellow except last tarsomer like
this one.
Here the anterior tarsomer is quite black.

Hello.
Although tis pict is fuzzy, a zoom on the fore tarsae shows that it is not quite black.
