..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

I saw these monkeys all in one day, in the lowland Amazon. I almost fell out of the canoe seeing the endangered spider monkey. An incredible forest 🧪🐒

Hello there. Here’s the 1st wonder of the world- a peacock katydid displaying for us here in the Amazon 😍

Caterpillar? Don’t want to be eaten as a snack? Here’s a popular strategy I found this week in the cloud forest.

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.

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.

Some vertebrates I found in Southeast Alaska. (It was really great to finally see bubble netting)

The entrance to Fords Terror. A fjord just off of Endicott Arm in Alaska. You can only get into (or out of) this fjord at high slack tide- for about twenty minutes a day. More photos of the stunning effects of glaciers on mountain rock soon to come

A weevil at Wildsumaco in Ecuador. Easily found by following the trail of glitter he leaves behind everywhere he goes.
But really- this glitter weevil is always amazing to see and a real wonder of the world. Endless forms most beautiful, indeed.

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

!. 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 :)

Just got back from Ecuador, where I made new friends, learned new things, and saw some cool stuff! Ecuador is a country that NEVER disappoints.
This gorgeous red huntsman spider is Sadala rauli, a rainforest inhabitant that I see quite often but was only formally described as a species a year ago!

Come take a hike on Antpitta Trail they said... 🐌 👀
Antpitta is right behind the biological station at Wildsumaco, Home of untold wonders, like these Giant South American Snails— and most of the other stuff I post on here. It is a real privilege to live in the same time on earth as these guys.

A game I get to play often in Ecuador… One of these things is not like the other.
Do you see him? Imagine looking in an entire forest.

A portrait of the charismatic Crayola Katydid (Moncheca sp) hanging out at Wildsumaco in Ecuador. Having held SO many similar (Copiphorini) katydids, it’s jarring to be met with these bright, in your face colors. Other than being purple this guy, and his green relatives, are excellent grass mimics
