I had a feeling that I’d see my first #dragonfly of the year today & I was right 🙂
A new species for me too – a male hairy hawker (Brachytron pratense) sunbathing in the grass 😻
Initially similar to other hawkers, like the migrant (Aeshna mixta) which I see a lot of, the hairy hawker flies much earlier in the year & is, well, hairy 🤷♂️🙂
Anyone know what the pink blob is under the anal appendages?

♀️ Detail von einem Vierfleck 🇫🇮
ℹ️ Der Vierfleck (Libellula quadrimaculata) wird bis zu 4,5 cm lang und erreicht eine Spannweite von bis zu 8,5 cm. Damit gehört er zu den Großlibellen. Gut zu erkennen ist das Tier durch die 4 Flecken am Vorderrand der Flügel, woher das Tier auch seinen Namen hat 😉 .
Redis changed to dual license. I'm migrating to Dragonfly! Even if I'm not personally hit by this, it's not longer truly open-source, so I exit Redis. Moreover, Dragonfly is also much more performant.
@brawaru Also they promised to keep the project open-source under 3-clause BSD license (it's a lie):
"Furthermore, the core of the open source Redis project will remain under the 3-Clause BSD license, and as expressed by the new governance structure for Redis, the project will be guided by a core team of contributors from the community selected according to their involvement and contributions. "
Dragonfly
This photo was taken a few years ago in Miner’s Marsh in Kentville reserve, one warm August noon. I hadn’t even seen this beautiful creature as I was busy photographing the sandpiper featured in the post from the other day until Steven pointed it out, so thanks to him for this summer memory on this snowy day today. Wherever these are now, we’ll see them again soon. Full post here: https://www.elliekennard.ca/dragonfly/ #bugsOnMastodon#Dragonfly#EllieKPosts#insects#wildlifewednesday
Besides next gen helicopters for Mars and Titan, here are 2 prelim. studies funded by the NIAC (NASA Innovative Advanced Concepts) program this year.

Range: 179 km at 1 km altitude
Total range per Martian year: 16,048 km
The Dragonfly astrobiology mission by NASA and APL will deploy a large rotorcraft on Saturn's moon Titan.
The quadcopter will host multiple instruments to assess Titan's microbial habitability and study its prebiotic chemistry as it hops across multiple diverse locations.
This dragonfly was busy moulting or being dead or something. It ignored me completely. The intricacies of the pattern on its abdomen are awe-inspiring.
