Tasmanian darner

The Tasmanian darner, (Austroaeschna tasmanica), is a species of large dragonfly in the family Telephlebiidae,[2][4] which includes some of the world's largest dragonflies. It is found in Tasmania, Australia.[5] The species was first described by Robert Tillyard in 1916 and inhabits streams and rivers.[4]

Also referred to as "hawkers", the name "darner" derives from the fact that the female abdomen looks like a sewing needle, as it cuts into a plant stem when the female dragonfly lays her eggs through her ovipositor.

The Tasmanian darner is a stout, dark dragonfly with a very dark colouring and light markings. It appears similar to the lesser Tasmanian darner, Austroaeschna hardyi.[4]

gollark: The map data is generated from crawling the "distributed hash table" somehow, and apparently only has the tree structure generated for routing somehow, *not* the list of all the inter-node links.
gollark: The map displays the entire network as a *tree*, though, instead of the actual *graph* structure, I think because they can't read the full data out somehow.
gollark: Yes, it™, because osmarks.tk™ is one of 939 mapped nodes.
