galled inflorescence

Macrolabis laserpitii on Laserpitium latifolium

detail

gall

the pedicels of a number of the umbellules are shortened, causing the umbel to take a globular shape, sometimes with a few normal umbellules extending from it. Larva white.

host plants

Apiaceae, oligophagous

Cenolophium denudatum; Laserpitium latifolium; Pastinaca sativa; Pimpinella saxifraga; Selinum dubium; Silaum silaus.

notes

The identification of the Polish galls shown above is not fully certain. The combination of necrosis and strong disorganisation, without a visible larva, leaves the possibility open of a gall mite infection.
