Does anyone know of any value of Jerusalem artichokes? And why are these two both called 'artichokes' when they're not related nor like each other as vegetables.  |
Why is the Peacock considered a pest as the adults would only feed on the nectar. The larvae feed almost exclusively on nettles, Urtica species, with a few records from Hops. I wonder whether their relative the
Painted Lady might use Cardunculus species as larval food plants as they regularly use various thistles + a range of other plants are also occasionally used.
