Rubus arcticus

Rubus arcticus (Arctic raspberry)

The larvae feed on Rubus arcticus, Rubus caesius, Rubus chamaemorus, Rubus fruticosus and Rubus saxatilis.

The larvae feed on various Vaccinium species (including Vaccinium uliginosum, Vaccinium oxycoccos and Vaccinium myrtillus) as well as Rubus arcticus.

Feli Fernandez (plant breeder and geneticist) told me that the original, complex cross was made by Elizabeth Keep in 1973 and involved 'Lloyd George', Rubus arcticus, R. occidentalis and R. idaeus strigosus.

The larvae feed on Filipendula ulmaria, Potentilla anserina, Potentilla erecta, Potentilla palustris, Potentilla tabernaemontani, Rubus arcticus, Rubus chamaemorus, Rubus saxatilis, Sanguisorba minor and Sanguisorba officinalis.
