Butterflies are seasonal in their occurrence. They are common for only a few months and rare or absent in others. The seasons when they are rare or not active as adults are usually spent either as caterpillars or as pupae. The months when the adults are active are called the “flight period”. Distinct flight periods naturally imply seasonality of the early stages of butterflies as well. Thus occur in different seasons (Kunte, 2000).
