Mantura obtusata (Gyllenhal, 1813)
mine
Full depth gallery, widening into a blotch. Frass in black threads. Larvae able to leave the mine and restart elsewhere. Pupation outside the mine. Neither the mine nor the larva can be used to separate this species from M. chrysanthemi, but obtusata has a preference for damper situations. Beetles metallic blue.

Polygonaceae, monophagous
Rumex acetosa, acetosella.
