Alternative food plants for Pterinoxylus spinulosus "Greenhills"

Since my nymphs hatched, I been trying different food plants since in my area there is no bramble, so the options were: Guava (Psidium guajava), Oaks (Quercus robur and Quercus rubra)Tilia sp and others.

The preferred food was undoubtedly Quercus rubra followed by Quercus robur and by last Guava. Tilia leaves were not accepted.

Hope it can be of some help for people who live areas where bramble is not available.
