That moment when you find a whip spider chewing on rainbow candy in the middle of the Amazon... Heterophrynus batesii, one of the most impressive arachnids in the Amazon area, seems to like feeding on the colorful Hyperphrona gracilis katydids. I see this scene very often on my visits to the region.

The Hawaiian Common Moorhen, is an endangered, endemic subspecies of wetland bird found exclusively on the islands of Kaua'i and O'ahu. There are only an estimated 1,000 of these birds remaining in the wild. They construct woven platform nests over shallow water. Chicks swim hours after hatching.

There are currently only 25 iNaturalist observations of this stunning spider, Micrathena furcula! Over 100 Micrathena species have been described, and all of them are equally awe-inspiring to behold.

Pseudoscorpions have been a bit thin on the ground lately, I've drawn a blank at 8 churchyards in a row now so finding this little Roncus lubricus on yesterday's bike ride was even more special than usual. Only 3rd one I've found.
A little pseudoscorpion with large reddish claws held tucked up and pulled back against its sides. The pseudoscorpion is on a dark grey piece of old roof slate and is facing left. Its body is a pale yellowy-brown colour.A little pseudoscorpion with large reddish claws held out in front of it as it walks off to the left on a dark grey piece of old roof slate. Its body is a pale yellowy-brown colour and the legs are almost transparent. It has just one pair of eyes (several other species have 2 pairs, some have none).

let me share a little story about a remarkable wasp that I encountered yesterday in our local deserts I stumbled across her, and scrambled to get a few crappy photos .... but then realized that she had a burrow, perhaps a better photo op was possible ?? here she is at her burrow entrance.

!. 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 :)

Wonderful weevils and mimic on @bsky.app Part II, Pachyrhynchus moniliferus, from The Philippines. Another colour variation. Striking patterns warn for posion. Found in old stable ecosystems. Hence much more vulnerable to deforestation and habitat fragmentation. #natureprotection #coleoptera #beetle

Lady Red-bellied Woodpecker on a wintry day. It's interesting being able to see those pointy tail feathers. The feathers, along with a strong lower back, help prop up the woodpecker while it is clinging and moving vertically on the side of a tree.
A woodpecker perched on a bare branch. She has a white chest and belly, red near the beak and on the nape of the neck, bald and white wing feathers, and pointy black and white tail feathers.

Psst: carcinization is not inevitable! R is for Raninoides, one of the best examples of DEcarcinization. It's a true crab, but its body is elongated and the abdomen sticks out. The wrench and spadelike appendages, and torpedolike body, are good for burrowing (see video, next skeet) #CrabAZ 🦀🧪🦑
Dorsal view of Raninoides benedicti alone on black background. Photo by Arthur Anker. 

Very elongate, carapace at least 2x as long as wide, true crab. Small abdomen is sticking straight out the back. Claws look like wrenches and multiple distal segments of the legs look like spades. Crab is brown with orangeish mottling. Limbs have blue edges.

Happy Valentine's Day! 🌹❤️ Here's my requisite heart-shaped-structure-or-color-on-arthropod pic. Very nice species. #Cerambycidae: #Saperda tridentata North Carolina, USA
A red and gray longhorn beetle crawling on white, shown vertically so that a gray patch looks like a heart. It has three of these patches. Outside the beetle it has an "I' to the left and a "U' to the right to say I heart U. An insect message says "but mostly Saperda tridentata loves elms"

Good morning, please have a nice bug*. #invertebrates #BugADay #Bugsky *Uhhh a jumping spider of some kind in Philadelphia standing on some moss.
A spider with iridescent green fangs and tan-brown legs and arms and black eyelashes, stands on some brown moss. It's looking into the distance, i can only imagine singing "I dreamed a dream" like Susan Boyle.

I think my best macro photography was with the Canon MP-E 65mm lens. Look at the glorious detail in this shot. It makes me want to bust that lens out of retirement. Tiger Fly (Coenosia sp.) Pennsylvania
A fly with red eyes and a gold body. You can see lots of hairs all over the body and the texture of the exoskeleton. The fly is standing on a leaf.

A jumping spider looking into the camera. The legs are light yellowish and the pedipalps and the part underneath the eyes are white. The rest of the body is reddish with a pattern on the abdomen. The spider is lifting its abdomen up. The spinnerets at the end of the abdomen are well visible.

Hello #PortfolioDay! I'm Rebecca, a science and medical illustrator who loves birds and other feathered creatures 🐡🪶🧪
Portrait of a female Great Hornbill, a large bird, down to the upper chest. Her beak is huge, with a yellow-to-orange maxilla and damaged casque and a pale blue-grey mandible. She has a black mask covering her face and the base of her bill. Her eye is silvery and has nice lashes. Her neck shades from yellow through raw sienna to a pale burnt sienna, and her body feathers and the top of her wing are black.Twelve detailed vector illustrations of brains, arranged in two columns, one without blood vessels and one with. More anatomical layers are added from top to bottom, starting from a midsagittal view and ending with lateral. At the bottom left is the wordmark "MedStudy", for whom I did this work.Gouache painting of Anchiornis huxleyii, a small feathered dinosaur, climbing through branches. He's mostly grey with black-spotted white wing, leg, and tail feathers and a rusty red crest and cheek feathers.Watercolor illustration of a Red-and-yellow Barbet, seen at 45°. His head is mostly red and his belly is creamy white. His wing is black with white spots, and a band of this pattern circles his breast. His tail is banded black and white. He's glaring at the viewer, challenging the audacity of any who would dare to look upon him.

Alguns besouros aquáticos que já fotografei (Dysticidae e Gyrinidae). Esses bichos são super interessantes pois são capazes de ficar muito tempo submersos devido à capacidade de armazenarem ar em seus corpos (especialmente sob as asas). Podem ser predadores ou detritívoros generalistas
