Most species of petalurid dragonflies have a fossorial larval stage, which is unique in the Odonata. Larvae typically excavate burrows in soft peaty soils in mires, seepages or along stream margins, which are occupied by a single larva throughout the long larval stage. This paper reports on a study of burrow morphology in Petalura gigantea,…
Establishment of larval pits by Tachopteryx thoreyi (Odonata: Petaluridae): habitat modification by a non-burrowing petalurid
Tachopteryx thoreyi is one of only two species of petalurid dragonflies with a non-fossorial larval stage. In the context of questions related to the phylogenetics, historical biogeography and current distribution of the Petaluridae, the evolution of a burrowing larval stage in petalurids, which is unique in the Odonata, is of considerable interest. This paper reports…
