To see these beeflies, Australoechus sp, flying around in the Fynbos, SA, has to be 1 of my life’s highlights Many were buzzing around Micrdon capitatus, the heady catstailbush - a rare endemic to this region. Rare because of habitat loss (land clearance) & invasive species. Brilliant #beeflies

🖼️ Image 1 – Hypothetical reconstruction of the queen. This is what she might have looked like had she founded a colony instead of fossilizing after drowning in a water pool. The queen and her first nurse are shown tending eggs and larvae of two generations.
no reference earwig (hind legs need to be pushed back a bit and other anatomical inaccuracies) #dermaptera
Sólo vengo a recordar que tuve el honor de escribir un capítulo en el libro "Artrópodos: Las fascinantes criaturas que cambiaron la historia" Libro en el que contamos cosas muy curiosas sobre bichitos. Y tiene ilustraciones muy bonicas de @theafenogaster.bsky.social Feliz #DíadelLibro 🐝🦋🐞🐜🪰🪲😉

I recently posted a picture of a large Dorylus molestus army ant worker from Mount Kenya. Here is the same ant again, but this time in comparison to its smaller sisters. These ants are incredibly polymorphic, and the different worker types take on different tasks in the colony.
I dug up this old picture from Twitter, so here you go: Meet the Pterosaurs! #paleoart #paleontology #pterosaurs
My chapter - authored with @tattersdill.bsky.social - in the new Palaeontology in Public book is "The ‘Spin’ in Spinosaurus: inventing a modern dinosaur superstar", discussing changing depictions and attitudes towards this now A-list dinosaur - read it here: uclpress.co.uk/book/palaeon... #palaeoart

hello late #PortfolioDay !! I'm Avi! Full time artist, doing direction (and many other things) in animation, and paleoart in my free time. I'd be happy to work on scientific illustrations and reconstructions! I do both extant and extinct animals and i'm open for some work rn :) #sciart #paleoart
Devonion fishies Elpistostege (close relative of the famous Tiktaalik) and couple of bothriolepis swimming by. Needs updating but still thinking this is one of my better paintings I have done
