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

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

💀 Lo que la marabunta se llevó: competencia entre invasoras.

👀 El pasado verano, durante el XVIII Taxomara celebrado en Málaga, algunos socios de la #AIM tuvimos la oportunidad de visitar la ciudad y, entre otras cosas, sus #hormigas.

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.

thank you!!

⁉️ ¿Sabías que…? La comunidad de criadores, aficionados e investigadores del mundo de las #hormigas cuenta con un #FORO que ofrece un espacio común y permite generar, conservar y gestionar un valioso conocimiento.

yes i approve of that thinking

A series of grey-shaded line drawings showing the changing shape of the sail-backed predatory dinosaur Spinosaurus over the last 100 years, moving through sometimes upright, sometimes spiny, sometimes T. rex-like depictions to longer-snouted, "newt-tailed" versions.

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
