Pioneer is a common butterfly found in the dry
zone of low lands and sometime in wet zone, though not common in all year
rounds. Its best months appear to be between September and February (The Butterflies of Ceylon - D'abrera
1998). It
joins with migrating flights during North-East monsoons and mud-pudding with
other species can be observed too. Its larva feeds on plants of Capparaceae
family such as Capparis brevispina, Cadaba trifoliata, Capparis grandis, Capparis sepiaria, Capparis zeylanica (සුදු වෙළන්ගිරිය) and Maerua arenaria. Egg laying only was observed on Salvadora persica (මලිත්තන් /Mustard Tree) too.
