I would like to point out that the local people in Bolivia were already familiar with the new cat species, traditionally calling it "Tilcayo", a name honored by the scientists who carried it over into the formal scientific name Leopardus tilcayo.

Look. At. This. (!). A fungus spore landed on this weevil. Grew inside and caused it to climb to the top of this plant- while the fungus killed it. Consumed its body. Used that energy to shoot up a red fruiting body to release more spores. To zombify more weevils. A mind controlling killer fungus.

Just a murderous fungus having taken over a wasp and compelled it to die in a place advantageous to finding more victims. With its tiny spores floating off through the air in hopes of just one landing on an exoskeleton.. nothing in the rainforest wants anything to do with this little scene here…

Hello from a Frog Hopper and a spittle nest I found along the Napo River in Ecuador. All that foam is how the nymph frog hopper keeps itself safe from harm. I love this photo because if you look at the largest bubble you can see the nymph living in there(!!). Tiny little worlds everywhere

..I mean since you asked.. 😅 Here’s a baby katydid mimicking a wasp— he will wave those antennae around and move on the leaf JUST like a little wasp -&- next to him is a fly also mimicking a wasp- but pretending her ARMS are antennae. You can see her waving them around desperately trying to fool me

A view into the Amazon from Sumaco Volcano. So many little worlds playing out in the forest below. An entire universe of beetles and monkeys and birds and humans. You could spend all your life learning about the ants in one of those little trees down there. Overwhelmingly beautiful.

I found this rove beetle friend on the rainforest floor. They are so so fast, you can imaging me chasing it around with my camera just rolling around in the leaf litter. Just unbelievable colors. In person the rainbow iridescence is stunning. It’s hard to say much here beyond just wow.

What spectacular shades of blue. An iceberg just off the face of the Dawes Glacier in Southeast Alaska. That little spec in front of the upper left part of the berg is an Arctic Tern, absolutely dwarfed by this chunk of mountain-carving-ice.

🎶horror music🎶 Another cordyceps victim. This particular species of fungus is targeting a different insect. It’s taken over the bugs body and moved it up a tree, where it killed it and consumed it (leaving behind the exoskeleton) using the energy to grow those orange mushrooms and spread more spores

There have been THREE velvet worm (Onychophora) posts in the last day or so, requiring a megathread. I'll add one of their coolest fossils first, from when they were exclusively marine, drawn by @franzanth.bsky.social for @arthropoda-curator.bsky.social (see next 3 skeets in thread...) 🧪
Franz Anthony's drawing of Facivermis, a strange stem group onychophoran which has elongate, feathery anterior appendages for filter feeding. It is in a tube embedded in the sediment and has a blobby bit at the posterior end. A second individual is shown hiding in its tube, with only the feathery appendages visible

!. Look at this astonishing animal. My velvet worm friend lives on moss in the rainforest. He is ANCIENT. WAY older than dinosaurs, lobopods like him even make an appearance in the Cambrian- when multicellular life became trendy. You can find him today on a tree at Wildsumaco, in Ecuador :)
