Thank you very much, I have some Prunus domestica. I'll try to offer that.
I managed to get some Lacanobia w-latinum eggs. I looked on internet for some hostplants but I only found Genista and Polygonum, both plants that I don't have. Does anyone know more common plants that I can feed the caterpillars with? Other Fabaceae as Trifolium or Medicago, or which low-growing plants?
