Food plant
According to Griffiths' revision P. flavifrons probably eats any Caryophyllaceae with big enough leaves, and was once bred from Celosia (Amaranthaceae).

Big enough leaves...
seems to include just about anything. Chickweed leaves are tiny (maybe 1 cm by 0.5 cm), and these larvae moved freely from one leaf to another.
