Aeshna brevistyla (Blue-spotted Hawker/Lancer Dragonfly)

This is one of those potentially confusing species that goes by two different binomial names, Aeshna brevistyla and/or Adversaeshna bevistyla. Either way, it is widespread in Australia, which seems to refer to it as Adversaeshna brevistyla (Blue-spotted Hawker), and also occurs in New Zealand, where the preference seems to be for Aeshna brevistyla (Lancer Dragonfly).

Actually, of course, it’s the taxonomists that mess things up. The IUCN Red List has it as Aeshna brevistyla, stating that Adversaeshna is a sub-genus. Therefore, I’m going with Aeshna brevistyla. Dr. Paulson, who maintains the worldwide list, has both names as synonyms.

We did see this character both in Australia, at the dam in Stanley, Victoria, and in New Zealand where we found it at a couple of sites, Cape Foulwind and Slab Hut Creek.
