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: I mean, school is expensive, computers are... £200 or so for a very basic one?
gollark: Replying to https://discord.com/channels/346530916832903169/348702212110680064/747839510280405092This is somewhat bad. Although I imagine sending people computers would be cheaper than running school.
gollark: Okay, that might not be the reason.
gollark: Boris Johnson is insisting that it's critically vital and important that everyone go to school as normal, because he is an incompetent apioid.
gollark: Yes. It was (is, I guess, I don't have school yet) so horrible being able to get up at reasonable times, work in a pleasant environment, and not have to commute.
