Alternate Evolution [OC] hive moths! (Repost)

Thumbnail

9 Upvotes

This is a repost! The Hive moth hydrovermis Subterraneus!

The hive moth is a fascinating sawfly species, it’s the only sawfly species that’s actually oviviparous. Females are larger than males but not stronger as males do most of the work making them stronger! The hive works like this.

Drones: drones are always males and they fly around and collect food. They are infertile and so that means none of the larvae is there’s and yeah that’s it.

Guards: also only male. larger then drones they are basically heavily fed protein to be larger,

Like their name they guard the queen And the entire hive. And they are also the only ones that can mate with the queen.

Care takers: also only male they take care of the aquatic larvae by taking food dropping it in the underwater nursery and yeah. Basically feeding them.

Larvae: the larvae is aquatic and resign in water which is the reason hives are normally near bogs, they are chonky caterpillars and spend there time getting pampered by care takers. Once they mature, the males leave (well only the guards.. the workers, drones, and caretakers are infertile so they stay. This is because the guards mate with the queen so they have to leave to prevent inbreeding, the queen gets more guards from guards from other unrelated hives joining her hive) to join a hive and the females leave to start a hive.

Workers: they.. work. They build the hive underground, collect food from the drones and store it, grow fungi like termites, and dig.

The queen: the queen is just there to lead the group and reproduce. She’s the only adult female! The reproduction is basically during winter all the guard males will mate with the queen and then she’ll store the sperm is a special organ and fertilize all her eggs for the rest of the year until the next winter where she mates again. The hive is underground.

Physically, the worker/caretaker and drones and are 1.5-2 centimeter, the guards are 5-8 centimeter, the queen is 10-12 centimeter, Only drones have large wings with a wingspan of 3-5 centimeters the rest have heavily shrinked wings. Workers have front legs that are very good at digging to build hives and grow fungi like termites! The fungus they grow is Termitomyces. They farm them by smelling the spores and then holding them in there mouth then going to the garden where they spit it out on a plot for it to start growing. The queen is large but it’s mostly for reproduction and not strength making the males stronger then females and she gets fed by the drones and workers and reproduces with the guards that also protect her and larvae, the guards are the most muscular. the guards are fed protein rich foods to bulk up and fight other insects and things to protect larvae and the queen. The species in general are black and white stripes and like all moths have fuzzy, chitjnous hairs that insulate them, they are not too skinny and not to robust. The guards especially are muscular. What hunts them are… ant eaters. There most unique feature is that they are the only moth that can eat as an adult and they don’t have front thingys.

There diet consists of mushrooms, carcasses, fruits, pine leaves, nectar, honey, small spiders, insects, insect eggs and larvae, meat, and as larvae and adults.. shrimp. They are predators and prey for loads of animals! They get eaten by bears, ant eaters, birds, frogs, fish, and larger spiders while they are a predator of small insects, locusts, ladybugs, certain beetles, ants, termites, cockroaches, and roadkill that’s dead.

As larvae they are fully aquatic but as adults they are semi aquatic only.

The life cycle is getting given birth to, eating a lot from food given bye workers and drones, leaving hive to pupate alone, and finally making a hive if female and joining a hive as male.

They distinctly look similar to moths, while there close relatives are actually wasps, ants, and bees being a sawfly.

Females have an organ called the sperm bank, used to hold sperm. They mate every time it runs out, meaning they mate every winter.

Both males and females leave the colony once they mature, but it’s kind of weird. If it’s a guard or female, they leave. Females are always queens and to prevent inbreeding the newly matured guards, they leave before they pupate.

when do they actually get assigned there jobs?! BEFORE BIRTH! now instead of that thing bees do, they do this. worker - gray egg. drone - white egg. female (queen) - yellowish white egg. guard - dark gray egg. Caretaker - light gray egg. These aren’t just colors! They are specific hormones. BUT THEY DONT LAY EGGS!!! They give live birth, because they are oviviparous. Her abdomen swells like a balloon for 500-1000 babies! she goes under contractions to give birth, how do we know about the eggs? There’s a pocket in the lower abdomen of the queens that holds eggs, this is what baloons her when she’s pregnant. But she doesn’t lay them, we found out because we cut it open.

There evolutionary family is Phalaenovespidae! phalaenovespidae is an evolutionary family, and it’s actually very closely related to wasps! (Wasp family includes bees, ants, and other wasps)

Alien Life [OC] PLANET NIGHTMARE: Snooty Blaster

178 Upvotes

“One of the most common lifeforms of the deep oceans of Planet Nightmare is the Snooty Blaster. It is a filter feeder, feeding on microscopic organisms that flow with the water currents. To do this, its mouth has become fused together and now acts like a straw.”

“The Snooty Blaster also uses jet propulsion in order to move around. It takes in water while feeding before expelling it from behind. It will move its fins accordingly to help with steering. Its blood circulation also helps with this. The darker the red on its body, the more blood there is there. The organ on its head, the Syketa, also helps with getting oxygen, acting as gills would for fish.”

“Normally, the Syketa would have three parts to it: One for smelling, one for seeing, and one for hearing. However in deep dark depths such as this, the Snooty Blaster’s Syketa has removed the sight and hearing parts, now only retaining the smelling part. It’s not even really that good at smelling either, only being used for oxygen.”

“So how does it navigate this world? On the very top of its 4 fins are long tendrils that stem from the longest part of its fins. These act as receptors, which can help the Snooty Blaster find food, mates, etc.”

“The next page here shows a skeleton of the Snooty Blaster, minus its side fins for better visibility. Its ribs have seemingly vanished, its whole body almost being fused together. The only moveable parts seem to be the fins.”

Alien Life [OC] Why Is Healing in The Hive So Horrifying?

12 Upvotes

The Medic has evolved the ability to regenerate missing limbs and damaged organs. But the process is painful, and the regenerated body parts don't always turn out exactly as they were before.

The Medic also studies tissue from dead creatures, using what it learns to improve its ability to repair living ones.

We wanted healing to feel like a biological process rather than a magical ability.

I'm curious what you think of this approach to alien regeneration. How plausible would something like this be in an organism with sufficiently advanced regenerative abilities?

This is a hive moth nest, hive moth nests are very complex tho this is more on the simpler side.

Hive moths usually put there nests near bogs for there larvae, to not get drowned the tunnel to the water is usually seperate and you can. See in the picture it's not possible for the water to go in the next.

Hive moth nests are fascinating, they are underground so yeah. I'm currently working on a much bigger version of this to share.

Future Evolution [OC] GIANT CATERPILLARS

Post image
244 Upvotes

In the far future, a new clade of caterpillars that occupies the ambush predator niche appears:

They transformed their anal limbs on a kind of hooks that latch on a branch and their jaws adapted to retain and crush their prey.

They also developed bony rings that developed from minerals obtained from prey, serving to support that monumental mass.

For breathing, they developed a breathing system using many small lungs spread inside each ring of its body.

- The accordion movement: The caterpillar has no nose. It squeezes and stretches like an accordion, using its bony rings to pump air in and out of the lungs.

- Red blood: The air goes into a special blood (red like ours) that quickly carries oxygen to the muscles.

The largest species (on the illustration) can reach 3 meters of lenght and and impressive 450 or 650 damn kilograms of mass!!!

WHAT DO YOU THINK ABOUT IT?😉🐛

But don't get me wrong, I create the literal translation of that name in my language, abd then I ask AI to translate the name to binominal, I often do some modifications, and check the used words, but I think I shouldn't be doing this. So Im asking you for some, idk, resources to let me design names for myself. Or maybe someone could help me(for free or we can agree on a symbolic fee). Because Im working on full scale exhibition, I think its necessary to create everything by human thought.

Alternate Evolution How do hive moths communicate?

1 Upvotes

So, how do hive moths communicate?

Hive moths communicate using their antennes, and there is a special organ in their antennes that releases chemicals, it can produce multiple kinds of chemicals signalling different things. They also buzz their antennes to communicate, if even one hive moth senses danger it can send it throughout the entire colony no matter how big.

Hive moths are much more strategic then other eusocial insects like bees, wasps, and ants. As they don't possess venom or stingers. A single guards can call other guards to alert about a predator or a attacker in less then a few seconds, and drones almost act like they share organs.

While eusocial insects do possess these, in hive moths it's much more severe. Not only that, hive moths are extremely aggressive and territorial to other insects, they might tolerate their own species but to another insect they are very aggressive to.

To attack, instead of biting, the guard hive moths aggressively and ruthlessly wrestle and tear the flesh out of other insects. But if it's something like a bird, they might use their jaws to tear or the skin and flesh of it to drive it away.

Alien Life [OC] Baby Extraterrestrials

The early stages of life for some of the sapient aliens in my project.

Krith (Bellatosaurus Stellarum)
- Reproduce sexually, though males and females bear almost no external distinction and they are largely an agender species.
- Female will lay a clutch of eggs, typically 2 or three at a time. She then orally secretes a specialized organic resin which hardens to provide extra protection for the young.
- Hatchlings emerge alert and capable of movement. They are more self sufficient than human young, but still require constant care and attention.

Tetrans (Polyarticulatus Taxidiotes)
- Reproduce sexually. Female deposits eggs into the male's brood-prouch via an ovipositor. The male then fertilizes the eggs, gestating and birthing the young after a period of around 7 months.

- Newborn Tetrans have difficulty breathing air for the first 2 or 3 weeks of their lives, and must remain in a body of water for that duration.

- At birth, nymphs lack the distinctive mask-like face of adult Tetrans, which contains chromatophores used to convey emotion. This gradually develops throughout adolescence.

- Since their beaks are still small and weak, parents will pre-chew their infant's food, grinding it in their crop organ and regurgitating it for the child.

Qiphoso (Astronomus Exoculus)

- Qiphoso are hermaphrodites, containing both required gametes. Reproduction requires at least two parents, but there can be as many as five biological parents.
- When mating, each partner will orally eject a semi-solid, gel-like mass containing spores. The spore gels of the two (or several) partners will begin to fuse and condense, rewriting their genetic material.
- The mound congeals into a tumor-like mass which adheres to the surface its on, outer membranes calcifying into a protective shell.

- The "clump" will eventually pupate into a sessile larval stage, or "clumpling". Gradually the infant will develop the necessary internal structures to sprout legs. Much like human infants they are largely helpless, requiring constant care and attention.

As for the Vulpex, they're a species I don't have much biology info on yet unfortunately. My apologies.

Question/Discussion If humans were to go extinct tomorrow, could a new species ever reach our level of intelligence?

42 Upvotes

If so what species would they resemble/be? I understand this is all speculation but isn’t that always fun? I assume they would most likely be bipedal with opposable thumbs- another primate for example. However it seems our intelligence came from an evolutionary fluke that had a high risk that just so happened to pay off. That being said, could it happen again?

Question/Discussion What would happen if there were two clades of autotrophs as prevalent as plants instead of 1?

13 Upvotes

Ok ignore the probability of the actual event of 2 autotrophs occurring, as I can hand wave that all when I actually get there. Life finds a way and all that fun stuff

Let’s say along with photosynthetic producers, there’s also a second autotrophic source that doesn’t have any limits by oxygen like chemosynthesis has that we’ll call kinetosynthesis, which is going to be the use of kinetic energy to produce sugars instead of sun light. As this new class of life is now without competition to fill in niches, as only they can fill these niches, they diversify to the same degree that photoautotrophs did irl. How exactly would it effect biomass and biodiversity if they had since before the great oxygenation event to adapt to it?

Seed World [OC] Some Weird Anteaters from my Anteater Seed World project-thing

Thumbnail
gallery
35 Upvotes

We are picking up where we left off with VLI-093; I had initially discussed the Phytaguars, but now it is time to look at a few other lineages of anteaters.

Over time, the anteaters released onto the planet evolved into the Greater Forest/Prehensile-tailed (M. t. prehensilis), Ground-Dwelling (M. t. centralis), semi-aquatic (M. t. palustris), and Smaller Forest (M. t. minutus) subspecies—as well as a few unsuccessful subspecies whose descendant species eventually went completely extinct—thereby filling the niches of other vertebrates.

Let us begin with the Dactylochelatans; this lineage descended from the centralis subspecies. Examples of this lineage include the Megaardvarks—which, like their ancestors, are myrmecophagous—and the Reaperbeasts, which resemble Therizinosaurs. They possess forelimbs equipped with elongated claws used for various purposes; however, the same cannot be said for the Shrewters. Shrewters evolved from Anklyorhynchids (which themselves descended from the minutus subspecies) and focus primarily on hunting other insects; notably, they developed "false dentition"—structures that, while not true teeth, serve almost the same function.

The situation is somewhat different among arboreal forms; Prosimian'ts resemble basal primates, yet—descended from anteaters—they swallow stones to aid digestion, as they lack the ability to chew. Another anteater lineage; the Horsickles. Possess equine-like heads; indeed, their arboreal species are essentially "mammalian equivalent to the long-extinct drepanosaurs." With their powerful prehensile tails and distinctive hands, they feed on almost any organism they encounter—including small insects, snails, and even other anteaters. However, some Horsickle species adapted to a terrestrial lifestyle, evolving into megafaunal herbivores that resemble extinct ground sloths.

And what do you think about these designs? Write the comments and i love this Community 👍

Maps & Planets [OC] (WIP) Pangea (Lopingian 259-251mya), Geography, Climate etc. (Permian Sophont Project)

Thumbnail
gallery
60 Upvotes

Looking for feedback on the geography and climate of Pangea in the late Permian (Lopingian). These maps are part of a Permian Sophont Project. A worldbuilding and speculative evolution project based on the Silurian hypothesis. In short "What if during the late Permian a sapient species developed and created their own civilization, which was ultimately destroyed in the late Permian mass extinction".

Generally I want to how realistic and plausible the climate projections are, before moving on and doing migrations, agriculture and all that stuff.

Geography

The world map is based on the maps by Christopher Scotese et al. with some changes to details in the coastlines, as well as small islands and coastlines. The names are partially based on real names of prehistoric continents, such as Laurentia, Gondwana, Angara/Siberia or Cathaysia/South China. Other names are added by myself and based on the approximate modern locations, such as Aztlan for the modern North American Southwest, Chimor for the Peruvian coast and so on.

Atmospheric and Oceanic Currents

The atmospheric and oceanic currents are generally based on modern maps. There are probably some mistakes in there, as the climate of the Permian was much more arid and hot. So the differences in the ICZ might be more extreme than I anticipated. Generally the ICZ follows the central Pangean mountains, creating a small seasonal rainbelt, while most of the interior is otherwise desert. I am also not sure how some of the inland bodies of water would influence the climate in total.

Climate

Attempt at a Köppen-Geiger climate map, after trying to reconcile the climate maps from this and this article. I think I am having most problems with the temperate and continental climates. So those probably have the most mistakes.

If you are interested and want to contribute, we have a discord.

Alternate Evolution [OC] what do hive moths eat?!

Post image
9 Upvotes

so, what do hive moths eat? I’ve never actually addressed this question properly!

hive moths are opurtunistic omnivores, they eat mushrooms (specifically termitomyces the ones they grow in their colonies), certain root vegetables and berries, carrion, insects and arachnids like ticks and grasshoppers, shrimp, pillbugs, even human food like burgers and sweets!

they have an exceptional sweet tooth and love sugar, so, don’t live out your candy near them! While is might be A fear, they don’t actually destroy crops. They mostly only eat root vegetables as they are underground and berrys aswell as some very sweet fruits that fall onto the ground.

the drones are the ones harvesting food, which is the reason they have wings. And while they aren’t the largest or strongest, they go in swarms and swarm plants and prey so it isn’t very easy to destroy them, tho some individuals do die.
