Chinese tussar moth (Antheraea pernyi) By: Oxford Scientific Films From: The Complete Encyclopedia of the Animal World 1980

Hey there. So, as a personal side project, I might be making a fanmade region based on China, and so far I'm trying to flesh out the invertebrate side of things. Specifically, I'm going for ones that are native to or common there. So far, I have:

Silk moth (Bombyx mori and Antheraea pernyi) [Bug/Normal] When I was making these, I had no idea you did a Bug/Normal silk moth. Oops...

Chinese luna moth (Actias dubernardi) [Bug/Fairy]

Blue carpenter bee (Xylocopa caerulea) [Bug/Steel]

Chinese hourglass spider (Cyclocosmia ricketti) [Bug/Psychic]

Shanghai hairy crab (Eriocheir sinensis) [Water/Dark] Making this one pirate/thief themed due to being an invasive species. Also crab claws + pirate hook?

Hallucigenia [Rock/Psychic] A bit on the nose, but I'm fairly surprised the fossils were actually found on

Any ideas on what other arthropods (or invertebrates in general) I could add? Thanks.

Those are all fantastic ideas! My silk moth is actually bug/fairy, and either way you can't pass that up for a China-inspired region.

What comes to mind first for me would be a Chinese Mantis, possibly inspired by the mantis-style martial arts. You could even give it two forms based on northern vs southern style.

There's also the Chinese Golden Earth Tiger tarantula Cyriopagopus schmidti, a large burrowing species with gold and black coloration, tiger-like stripes on the abdomen, and a prominent white "beard". I read that it might have inspired the legend of the Tsuchigumo, which I used to make a Bug/Dragon pseudolegendary, but it's one of those concepts I'd love to see someone else's take on.

A caterpillar infected by Ophiocordyceps, though it might be cribbing too much from Paras and Parasect.

A polychaete worm (such as Phyllodoce citrina) stylized into a Chinese dragon.

A hammerhead worm (Bipalium spp)

Just a heads up. This post is about moths and larvae stages. This is because I'm considering having a demon with moth or butterfly abilities attacking Sigfrid in a drabble or a roleplay in the Demon Slayer verse. I might make headcanons for Sigfrid as he turn into this kind of demon as well. Either as he's half way turning or turning all the way. I'm still briefly doing research from wikipedia so take what I'm saying with a grain of salt. I'll try finding other sources. Antheraea yamamai - Wikipedia To start off I wanted to look at what kind of moths are common in Japan. One moth that showed up was the Antheraea yamamai - Japanese silk moth or Japanese oak silk moth. The japanese name being yamamayu(ga) (山繭(蛾)・ヤママユ(ガ)) or tensan (天蚕)). The moth create a strong and elastic white silk which in modern times is rare and very expensive. The moth is wide spread in asia and has been cultivated in Japan for 1000 years and has been imported to Europe for tussar silk production. Here are two pictures of the Japanese oak silk moth, a picture of the larvae stage and a cocoon.

What is tussar silk then? This is what wikipeida says: "Tussar silk (alternatively spelled as tussah, tushar, tassar,[1] tussore, tasar, tussur, or tusser, and also known as (Sanskrit) kosa silk) is produced from larvae of several species of silkworms belonging to the moth genus Antheraea, including A. assamensis, A. paphia, A. pernyi, A. roylei, and A. yamamai. These silkworms live in the wild forests in trees belonging to Terminalia species and Shorea robusta, as well as other food plants such as jamun and oak found in South Asia, eating the leaves of the trees on which they live.[2][3] Tussar silk is valued for its rich texture and natural, deep-gold colour, and varieties are produced in many countries, including China,[4] India, Japan, and Sri Lanka.[5]" From my understanding silk comes from different silk worms as they build cocoons before going through metamorphosis. When collecting silk for production the larvae is either killed by being dried in the sun. Another method is to let the larvae leave before pouring boiling water to soften the silk which makes it easier to collect. Enother method is to boil the pupa while the larvae is still inside. Tussar silk - Wikipedia I mainly looked at this kind of moth because it's a silk moth which has an important role in silk production and has been an important part of trading historically speaking. I thought it could be a parallel to Sigfrid who's a foreigner and also married to someone who is in charge of legal and illegal trading. I imagine Sigfrid would be starting of as having larvae features as he is partly or fully turned into a demon. If or when he's fully turned he would then look like a silk moth larvae until he build a cocoon and then turn into a moth. The moth can be seen as a symbol for increased silk production, modernisation and globalisation. If there is a big demand for a product it's most often a signal to increase production.

Moths have developed what scientists describe as a "stealth cloak," making them nearly invisible to bats' senses. Researchers at the University of Bristol are working to mimic this feature to produce more effective sound absorbers, creating what they call "sonic wallpaper."

Silk’s Nano-Scale Fibrils Give It Cryogenic Toughness to Thrive in Outer Space Temperatures

Their initial discovery had seemed like a contradiction because most other polymer fibers embrittle in the cold. But after many years of working on the problem, the group of researchers have discovered that silk’s cryogenic toughness is based on its nano-scale fibrils. Sub-microscopic order and hierarchy allows a silk to withstand temperatures of down to -200oC. And possibly even lower, which would make these classic natural luxury fibers ideal for applications in the depths of chilly outer-space.

The interdisciplinary team examined the behavior and function of several animal silks cooled down to liquid nitrogen temperature of -196 oC. The fibers included spider silks but the study focused on the thicker and much more commercial fibers of the wild silkworm Antheraea pernyi.

In an article published October 3, 2019, in Materials Chemistry Frontiers, the team was able to show not only ‘that’ but also ‘how’ silk increases its toughness under conditions where most materials would become very brittle. Indeed, silk seems to contradict the fundamental understanding of polymer science by not losing but gaining quality under really cold conditions by becoming both stronger and more stretchable. This study examines the ‘how’ and explains the ‘why’. It turns out that the underlying processes rely on the many nano-sized fibrils that make up the core of a silk fiber.
