DESCRIPTION

---

Large, sometimes robust forms with large eyes which may meet at the top of the head. They may be distinguished from the Zygoptera characters and by the form of the forewing which is less broad at the base than the hindwing. Nymphal Anisoptera may also be distinguished by their more robust form and by the lack of caudal gills on the abdomen. Adults at rest hold their wings outstretched as opposed to along the back as in Zygoptera.
