Emergence behaviour in Petalura gigantea (Odonata: Petaluridae) : confirmation of upright emergence

Two distinct emergence styles have been reported in odonates, with both the upright and hanging back emergence reported in the Petaluridae, between and within individual species, including Petalura gigantea. This paper reports three additional observations of upright emergence in P. gigantea, providing further evidence that this emergence style is the norm for the species.
