DioptinaeJames S. Miller and Andrew V. Z. Brower
This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

The Dioptinae are an almost exclusively neotropical group of day-flying moths, many of which exhibit bright wing coloration and are involved in mimicry rings with butterflies (especially Ithomiini), sterrhine Geometridae and various arctiids. The two specimens illustrated above are representatives of the type species of Dioptis and Josia, the type genera of the two tribes indicated here.
CharacteristicsSmall, delicate, mostly day-flying Notodontidae which are frequently confused with similarly marked Arctiidae and Geometridae. Miller (2009) points out that the easiest means to distinguish a dioptine is by (1) presence of a metathoracic tympanum, which separates it from Geometridae, whose tympana occur on the first abdominal segment; and (2) a trifid forewing venation, as opposed to quadrifid venation in Arctiidae.
Although numerous authors have described individual species of Dioptinae, the list of works cited below includes historical and modern efforts to revise the entire group. The classification presented here and in subordinate branches is based on the most recent of these (Miller, 2009).
