1. The taxonomy of Lepidoptera has recently been updated based on new evidence from morphology and molecular data.
2. There are now 4 suborders: Zeugloptera, Aglossata, Heterobathmiina, and Glossata. Previously there were only 3 suborders.
3. Within the suborders, there have been revisions to some superfamilies and families based on relationships between groups being clarified. The new classification aims to better reflect evolutionary relationships between Lepidoptera groups.
