Leaf-mimicking katydids like this Cycloptera speculata are among my favorite to encounter when I visit the Ecuadorian Amazon. They really look and behave like a leaf, and if that's not enough they also show a high degree of color pattern variation to depict leaf damage like holes and sunburn marks.

When you see this fly, be kind. It just wants to hug you and never ever let go 🤗 ever

A funky Pholcid from Mexico. I had no idea that there were Cellar spiders with weird heads. Weird heads are one of my favourite features a spider can have. Modisimus sp. #Pholcidae #CellarSpider #iNaturalist

Always a treat to see; a lovely Ruby-tailed Wasp in our #Staffs garden yesterday. #wasp #CuckooWasp #SolitaryWasp

It is a unique pleasure to have someone send you pictures of a species you described. It's like a report that one of your kids is doing all right. This beauty is Orectoscelis westwoodi, a myrmecophile (probably with Pheidole) described back in 2005 from Queensland, AU. (photo by Jan Pražák)

You need these bebes in your life

An amazing artist's rendering of Heterophrynus

A change of mood: cloud forest in Boquete, Panama.

Let me tell you the magical story of the #TrilobiteMoth, a mystery that followed me since 2002 and has finally been (partially and almost) resolved thanks to the dedication of fantastic entomologists from all over the world collaborating on the fantastic platform @inaturalist.bsky.social ! 1/xx

Model and mimic: a clever longhorn beetle (Euderces reichei, at right) tries its best to look like a local carpenter ant, Campontous decipiens, as they both feed on a spring dogwood flower. Brackenridge Field Laboratory, Texas.

I've always admired Skink's sculptures of insects. I even wrote about it a few years ago: gilwizen.com/skink-chen/

Summer storm rolling through the Perth Hills ⛈️🌩️ Sound up for the lovely rumble of thunder Here’s hoping this gives us a good bit of rain 🌧️🤞 #weather #storm #thunder #PerthWeather #PerthStorm

「日本の海にこんなヤドカリいるの！？」ってよく言われる子

Sharing more Costa Rica memories in anticipation of next year's photo tour... The first couple eyelash vipers I ever saw in the wild were pretty drab. They come in different colors (including brown, grey, and dull green). So finally seeing the classic bright yellow version was pretty awesome!

Finally, the bug is back with a round of the Guinness.

A sphinx moth came to slurp at a desert lily as we were watching the sunset over the Anza Borrego badlands.

Last year I dedicated six months to only shooting and editing for my UV floral series. Just one long flow state. I highly recommend the experience for anyone creative. If you can't swing that kind of time, just keep in mind what sick days are really for: making art. #flowers #photography

These Florida harvester ant major workers never looked real to me. Just a ridiculously large head tacked on to a regular harvester ant body. Archbold Biological Station, Florida.

Amazing story of a moth once thought extinct being recorded in the wild after 150 years! This story shows the power of platforms like #inaturalist and the value of a #bioblitz, with this moth recorded during the Great Southern BioBlitz 2021 @gsbioblitz.bsky.social #mothsmatter #inverts #bugsky

Look closely

Beautiful drawing of Thyrsocera spectabilis

Here are a couple of the underrated finds from our night walks in Guyana. Trying to ID obscure bugs is always a challenge, but @wizentrop.bsky.social was there to help me once again. Turns out these two critters (Largus anticus and Dubiepeira neptunina) have rarely been documented in the field!

If you follow me on IG/FB, you may have seen my Stories and know I’ve been leading my Guyana tour the last two weeks. I hope to share photos from this trip soon. In the meantime, here’s a short video from the most unexpected moment of the trip (I was looking for birds and didn’t have my camera).

Very exciting day today, as we can finally attach a species name to this mysterious and beautiful hawkmoth caterpillar from Ecuador and Peru. Thanks to the rearing and documentation efforts of @gwentomologist.bsky.social, we now know this caterpillar is Manducta neglecta.

Definitely one of the coolest shots shared by my peers in this year’s year-end collection from other photographers! @wizentrop.bsky.social photographed this Micrathena spider constructing her egg sac in Ecuador. Read more about it in the blog. (Photo © Gil Wizen. Shared with permission.)

Did some work on my #FungiJournal the other day. A work in progress. I’ll finish it one day. Music: Detectorists - Johnny Flynn. #FungiFriends

There is impossible wonder in the forests of city state Singapore. I find indescribable magic in the shiny eyes of this beautiful, peaceful Sunda Colugo.

Bro is LOCKED IN! 🤠 Check this out! An inseparable mating pair of Leaf Mantids (Pseudoxyops perpulchra) from Ecuador! 💚 That small male at the back is hanging on for dear life! We all know what the female will do if she gets the chance! 😅😈

The thing about entomology is, there are always weirder bugs than anything you could imagine on your own. Here's Cysteodemus wislizeni, a blister beetle from west Texas.

Australian cockroaches are pretty. This is Balta spuria, which I've found in various indoor and outdoor settings in Victoria.

I found some tiny crabs in the sea 🦀✨️ It felt just like a crab kindergarten!! ⁡ かにがにの多様性𓂃◌𓈒𓐍

Giant Leopard #Moths, Hypercompe scribonia, were frequent visitors to the bug light this year. What looks like black markings from a distance, is revealed to be a rich iridescent blue upon closer look. Some have spots, and some have rings. #MacroPhotography #Mothmas #Invertefest

The magic of Christmas Eve was another stunning male Atlas moth. My 5th Atlas of the week. Finding these magnificent magical moths means so much to me.
