Hello, hope you're doing well. What's that black thing at the bottom of your HS troll's feet? Is it padding or shoes?
I am indeed doing well, thank you! :)
Good question, and good guesses! I took a lot of inspiration from spider and beetle feet for my trolls.
It is particularly clear on the beetle feet (right) that the bottom of the foot has a pad of thickly packed hairs (setae). While in tiny arthropods these are largely used to stick to stuff, Trolls benefit more from the padding function.
In mammals, we've got nice big fat pads on our soles to cushion our bones from impacts. You can really see it on the elephant (right).
(forgive the quick sketch) The setae on troll feet does the same thing. They're dense, thick and springy. They also provide a barrier from sharp rocks and stuff, add surface area and friction for gripping, and give sensory feedback on what kinda stuff they're standing on, like whiskers. They've probably got a bit of movement to them too, to better adapt to different surfaces and the like by tightening or loosening the spread between hairs or changing how tense the spring is.
You may have noticed that I rarely draw Trolls with shoes on. Part of that is just I put a lot of effort into the feet to just cover them up (and I think they're cool), and part of it's that it's hard to design clothing for an alien species (shirts and neckwear is especially irritating with the way the rumblespheres are positioned in the front as opposed to humans' side shoulders, plus the sensitivity of the gillslits) but also any shoes would have to give a definite bonus over what bare feet would give them.
So you'd still want access to your toeclaws for both weaponry, grip, and mobility. And you'd want a lot more protection from the elements than the setae give you if you're going to sacrifice the sensory and movement aspects to put something with a sole on, plus you need to be able to put them on and keep them on without damaging the hairs or getting snagged on the claws, and anything that straps underneath is going to be awkward if the hairs can go on either side of the straps (though between the two toes is probably a good anchor).
I have done it a few times though! The ergonomics aren't perfect, but here the Distrait Life of Mistakes (@temporaldecay [deactivated]) crew aresacrificing that for fashion; theming their shoes for their misc/redrom, palerom, and blackrom rave gear respectively. (occurs to me the palewear shoes would be even more provocative with claw covers or softpaw nail tips; really lower your damage capacity. Oh well, too late :) )
Thank you so much for the question, anon <3!!

Would it even be possible for a Mother Grub-like creature to exist on a humanoid species scale without magic, considering the vast caloric intake it would need just to exist even without constant egg-laying? Speaking of, how fast do you think it could produce eggs? I'm trying to figure out numbers for the troll population and that's my starting point.
Woof, hmmm....
It's interesting because I have wondered some of these things myself before, wanting a place like Alternia or any other giant-animals & dragons world to be plausible, but I don't have the background to get into the actual science of it. But let's see how far I can get and then hope that someone else can fill in the gaps.
Okay, so the three major constraints we'd be working with here are: structural integrity vs gravity and square-cubed law, air intake and blood circulation vs square-cube law, and calorie intake vs food chains and square-cube law.
For those who don't know, the square-cube law is the principle that the mass/volume/weight of an object grows faster (x3) than its surface area (x2) or the measurement of its height/length/depth in one direction (x1). An ant, being much smaller than a human, needs proportionally less muscle to fight back against gravity. Its exoskeleton doesn't need to be made of a super-tough material to withstand most of the impacts it receives or to easily contain all the bodily tissues. It needs less oxygen and what oxygen it has can reach all its tissues even without a special tube system to pump it all over the place, and it can survive on a very small amount of calories. If you simply embiggened the ant to a human size it would collapse and be unable to breathe.
So let's take this one at a time: structural integrity Our mother grub needs to be made of much stronger material than an ant is. There is precedence for this, found in other animal kingdoms. Elephants manage to move around despite their size, as did the dinosaurs before them, with huge dense bones and similarly meaty muscles. And both the scaly-footed gastropod and some rodents integrate metals into their bodies to toughen their shells and teeth respectively.
This is an alien from a different planet and evolutionary tree after all, we do not have to stick to the traits we can observe in the insect kingdom on our own planet here. Calling trolls and mothergrubs insects or insectoid is simply a shorthand for convenience and we can decide that they've convergently evolved these adaptations or whatever else we might invent to allow them to work as we wish, we just have to make the actual function make scientific sense. So, the mother grub's exoskeleton is metal-infused, and she might have a secondary internal skeleton to hold her up as well, as a solid core to hand things on is more structurally sound and mobile than a can around it. Or perhaps a more honeycomb-like approach, with supports scattered throughout; like a building with rooms. Maybe it evolved in a kind of opposite way to how a turtle did, where it had an internal skeleton that then grew into a shell. Or perhaps it is a new structure that we do not have an equivalent for in our insects. Either way, that's the exoskeleton out of the way.
As for muscles, while I think it's possible for them to have evolved them to the point that they can have the typical thin limbs of an insect, since we can see that mechanical devices can operate under such contraints, I think it's likely that that the limbs in general and the weightbearing and locomoting legs especially are significantly chunkier than we would see on an ant.
I will say however, that it is entirely possible that the mother grub in particular is not especially expected to move around by herself, and typically relies on drones and jadebloods to do much of anything. Pretty sure that’s how termites do. Perhaps Kanaya's virgin mother grub is also smaller than she is depicted; though the opposite could be true and most mother grubs do not regularly attain such sizes and either the lusus fluke or her being unmated contribute to her being as large as she is. We simply do not see any other mother grubs, though the implication that the skull on Terezi's scale is from one would suggest that the inverse is true and mother grubs can be enormous indeed. Either way, she probably doesn’t fly unless she’s much lighter than she looks and maybe filled with helium. Perhaps the wings are decorative? Or maybe they function as part of a heat-dissipation system or even for oxygen exchange themselves?
In any case, onto the next issue: air and blood circulation
As you probably already know, insects have a much different respiratory system to vertebrates. Instead of a central hole or three to breathe from and a sac to breathe into, where it dissolves into the blood and then a bunch of tubes all around the body to take the blood to the tissues, they tend to have what are called "spiracles," a bunch of little holes in their skin big enough for the air to enter and a tube to take the air to the tissues directly. The problem with this on a large scale is 1: less surface area:volume means you have less space for spiracles, 2: more volume:size means it's harder to get the oxygen to all the tissues you've got packed in there. Letting the oxygen essentially just passively absorb just isn't very efficient.
In past eons some invertebrates have gotten around this to get much larger than they are today by the simple expedient of there being significantly more oxygen in the air than there is these days. We can also get a heck of a lot more leeway by updating our mother grubs to have a heart and blood and veins and such. Something more complex than the simple book lung that spiders and such have. For reference, while the largest terrestrial invertebrate that ever lived was a 110lb millipede we think that the blue whale is pretty much the largest an animal can get with a mammalian circulatory system before the heart just can't pump the blood through the body fast enough, and it comes in at 199 tons (two-hearted whale when).
So pump up the oxygen level (not too high or there's fire explosionsm especially under the alternial sun), and maybe decrease the gravity on the planet and things can grow pretty big. Maybe you could even switch out oxygen and carbon as the main elements we're looking at here and get a boost that way too. I’m not big on chemistry or how things work, so maybe oxygen and carbon are the only things that’ll work here, but for instance the atmosphere on earth is 78% nitrogen and only 21% oxygen and humans don’t even do anything with the nitrogen, so even assuming that humans have to breathe the same air as exists on alternia (not a safe bet, as each species would have some wiggle room in terms of air composition and all humans were godtiered and capable of surviving in the vacuum of space [or at least the medium] by the time they were face-to-face with the trolls, and Earth C is both dubiously canon and potentially contains species that are not quite the same as those on either earth or alternia) you’ve got plenty of space to fill with some alternate gas in there.
So we’ve got a metal-plated, well-muscled mother grub who maybe doesn’t move around so much and has anatamy containing lungs, pumped blood, and veins. Maybe she’s got spiracles still and they work like our own airways or maybe she’s got a big honker of a nose like humans do, but either way we’re cooking with fire here. We’ve made the planet lighter and changed the O2 content and maybe we’re working with a silico-hydrate base for all our flesh-building purposes and thicken up the air so it’s soupy and bouyant. Heck, maybe we shrink everything we see over on alternia and the trolls themselves a bit, and they’re only depicted as of equal size as humans for story reasons or maybe everything gets resized to a default setting once it enters the medium for convenience’s sake. Whatever, it’s not important cause now comes the problem that I keep running into headlong each time I try to tackle an alternia-like ecosphere. The food web.
Cause, see, the mother grub by her self and trolls as a whole, they’re not a problem. (Well, not until they start taking all those nutrients to space)
The problem is this: Lookit how many giant predators and hyper-predators there are. Lookit this dragon. That is canonically a newborn. She can fly and breathe fire. Lookit this horrorterror. She canonically eats a ton of land and surface dwelling meats and isn’t just subsisting off of chemical vents or something.
All that mass, the energy to go flying off into the sky with extra to (literally) burn? That’s gotta come from somewhere. And on the one hand, we have maybe a partial answer: the sun. Specifically, that it is implied to be extremely hot and strong and maybe close. Not explicit, since Trolls could be unusual in their being nocturnal and even looking at our sun for long will blind a person, but the implications are there and we can run with them to a big, hot, super energy source ripe for the taking. The problem with that is that energy typically doesn’t flow down the food chain very far. We like to think of the food web as being a self-sustaining perpetual motion machine, but that’s just not true. So much energy is lost at each step, often as heat. And then that heat dissipates into the atmosphere and then escapes out into the greater universe. Think about it; how many seeds does a bird have to eat to grow to its adult size, and then to sustain it every day? Then how many birds does a cat have to eat to do the same? And how many cats does a fisher eat, and how many of those does a puma need in its life? It’s a lot. It’s exponential at each step, since a creature must spend so much energy just maintining its daily life and can’t put it all on body growth. And then all of that big long chain has to be sustained on vast quantities of plant matter, who generate their own bodies from the sun. There is of course a secondary chain that “starts” with detrivores like fungus and flies, but is by necessity focused on a much smaller amount of resources than the main chain.
So we’re limited by the following:
- how much energy the sun makes
- the % of that energy that makes it to alternia
- the amount that bounces off alternia or its atmosphere before it can be harvested
- the % of that energy that photosynthesizers can harvest
- the % they can store
- the % they need to live and propegate until they are eaten
- how much the herbivore needs to grow and live and eat and reproduce
- the efficiency with which the herbivore stores the energy gain
- how much the creature that eats the herbivore needs to use
- how much ITS fat can store.
- and so on
We can mess with any and potentially all of the steps in the chain to increase potential length of it and allow more and more massive and widespread superpredators at the end of it. We’ve already started that by increasing the potency of the sun, but each change will have repercussions. For instance, if energy is so widely available then why bother to evolve anything more complicated than photosynthesis itself? I once heard an author say that one needs to have two levels of answers to worldbuild convincingly – to solve the first problem and then to solve the follow-up question. That after that people will be satisfied. Something about fighting nuns. Where did the nun learn to fight? In the sewers. Why was she in the sewers? To fight the crocodiles.
So: We amp up the sun. Why bother evolving herbivory? The sun is too hot and withstanding it is costly and resource-intense. Not everything can be a plant because not everything has the sun-blocking resources, and there is a niche for nocturnal herbivores who don’t have to invest in sun protection. Why carnivory? The sun-block also makes the plants tough and hard to eat and digest; eating meat is relatively quick and easy.
The same thing can be done at other steps. Maybe we make animal life on alternia more efficient: they can do all work of living without creating much waste-heat, and their versions of digestion and fat pack in more calories denser.
But again, the nitty gritty science is not my area of expertise, and these are the questions that can keep me awake at night. What kind of solutions could make the food chain more efficient? What kind of pressures would encourage long food chains, large fat stores, and giant hyper-predators? How can we engineer an environment that will predispose this planet to logically evolving dragons?

Timeline Notice
Save for a few exceptions, BugStuck is getting a makeover! What does this mean? Well > Positions are opening! Most of the roles that have been filled have become inactive, or have lost interest in the timeline, or what have you. So we're looking for some fresh faces to breathe new life into the timeline! > Headcanons are changing! Nothing extreme, just minor details here and there, like anatomy or backstory tidbits. > Speaking of backstory, there will be open characterization for all free slots! No shoehorning potential new members into positions they may not be interested in. As long as certain canon details are kept consistent, you'll otherwise have free rein. Now, as can be expected of an established timeline like this, these changes will take time, as certain measures need to be put in place and changes have to be made to the blog and rules. Continue following @bugtrolls for further updates!

on a very different note here is some giant-monster-bug!fantroll art.
regardless of what design/form he takes, I can't handle the cuteness of Pip's erhard seiros, nope.

Bloodlines Indigo - GHB
<ID> Digital art of the Grand Highblood, Gamzee's ancestor from the webcomic Homestuck; he is seated on a throne, snarling, and gesticulating with one hand while wielding a juggling club in the other. He is a gigantic, top-heavy troll; here depicted in a buglike, xeno style that segments his limbs and gives him a long toothy muzzle. The moody purple colour of the majority of the piece accentuates the golden shine of his long back-swept spiralling horns; on his prominent dentition - sabertooth canines and outswept flattened tusks jutting up out of his mouth from both top and bottom jaw; the gold continues on the razer-sharp scything claws on each of four digits on per hand and two per foot. </ID>
The Grand Highblood for the Makara edition of the Homestuck Bloodlines Zine. I based his teeth off of a combination of musk deer and warthogs. He was fun but tricky to do; I am not quite fluent in Blender, especially posing and the fancy modifiers and math and whatever, which was instrumental in this piece. With any luck I will be able to remember how I modelled his horns, since that will be a very useful skill in the future. It involved 3 parts, IIRC: modelling a small trisection, using a curved line to indicate the general horn curve and having the section repeat along it, and applying a spiral. There must have been a taper function used as well, I think that might also have been a curve? Looks like I have forgotten it all already! Oh well, I will simply have to re-learn it next time!! You can find the edition here. Bloodlines also has a caard, a tumblr, a twitter, and you can find the other editions at the itch.io You can also find me at tumblr deviantArt FurAffinity and Patreon.
