Fossil dragonfly-type larva with lateral abdominal protrusions and implications on the early evolution of Pterygota
Summary: Aquatic larvae are known in three early branches of Pterygota: Ephemeroptera (mayflies), Plecoptera (stoneflies), and Odonata (dragonflies, damselflies). A common origin of these larvae has been suggested, yet also counterarguments have been put forward, for example, the different position...
