Ametastegia glabrata

Ametastegia glabrata (Fallén, 1808)

Larvae free on the leaves.

host plants

mainly Polygonaceae

Bidens; Bistorta officinalis; Chenopodium; Epilobium; Fagopyrum; Lythrum salicaria; Plantago; Polygonum aviculare; Rheum rhabarbarum; Ribes; Rumex acetosella, crispus, longifolius; Salix; Solanum dulcamara, tuberosum; Vicia; Viola tricolor.

The full grown larvae, in preparation for the pupation bore themselves into stems of all sorts of plants, even woody ones. When later wasps are bred from these stems numerous fictuous host plant relations may result. According to Liston & Zerafa probably only Rumex species, some Amaranthaceae, and perhaps Solanum species are true host plants.
