Isatis tinctoria
In Morocco, the species is particularly associated with woad ("Isatis tinctoria"), and is found at mid and high elevations in the Middle and High Atlas Mountains. Larvae are often found on the same individual host plant as caterpillars of "Euchloe", "Pieris rapae" and "Pieris brassicae". Compared to these other pierines, "Z. eupheme" is associated with very stable environments.
