This butterfly owes its specific name to the River Tagus in Portugal, along the banks of which it was first found. The Portuguese Dappled White is found on warm, dry rocky places with patches of flower-rich grassy vegetation, in dry scrub, and on abandoned agricultural land. Various crucifers are used as foodplant, such as candytufts (Iberis spp.), including I. ciliata, I. saxatilis and Annual Candytuft (I. amara), and buckler mustards (Biscutella spp.). The caterpillars eat the ovaries and flowers. It has one brood a year and hibernates as a pupa.
