(i’m only surprised it finally happened in arizona; my money was on australia.) please rest assured this is very uncommon. hold on, I’m gonna take the opportunity to infodump about a special interest:
Spider x Scorpion Sex
ok so: spiders and spiders are occasionally observed mating in the wild. it makes a weird sort of sense: they are both arachnids with surprisingly similar mating rituals, so if two species have similar sizes and markings, a male performing a mating dance can end up attracting a cross-species partner. this happens particularly in times of lowered sexual competition, where for whatever reason there are fewer same-species partners to choose from. I guess if you’re horny enough, a strong healthy mate with the right number of legs (8) is all anyone can ask for. Personally, if i was a horny little spider looking to get some, I would still be concerned by the fact that scorpions eat spiders. But then again both groups include species that practice sexual cannibalism, so maybe that’s not such a turn off.
Unfortunately, spider/scorpion sex remains very much the exception to the norm. there just aren’t many areas where spiders and scorpions (of similar size, shape, and physical attributes) share territories, and have a sex ratio imbalanced enough to spur cross-species copulation.
Finally: when it does happen, spider/scorpion sex almost never results in offspring, for a couple of reasons:
a bunch of species aren’t genetically compatible, fertilization just isn’t possible
so far, the only documented instances of spider-scorpion offspring have come from unions of female spiders/male scorpions, so it’s probable that intercourse between male spiders/female scorpions just doesn’t result in viable eggs, for whatever reason.
side note: i’m actually really disappointed about this, bc it’s very possible we could have gotten two distinct types of hybrids per combined species, the way Ligers (female tiger/male lion) are distinct from Tigons (female lion/male tiger).
also spider-scorpion hybrids* are sterile (or at least the ones bred in captivity have been so far.) infertility is quite common among animal hybrids. it’s the reason mules (horse-donkey hybrids) can’t reproduce. the consequence is that itty bitty baby spider-scorpions probably aren’t going to grow up and start massive colonies families of their own, sadly.
(*here i need to make a correction to the original post: the correct term is “spider-scorpion hybrid” not “scorpion-spider hybrid”)
For all these reasons (rarity of naturally occurring spider/scorpion intercourse, the unlikelihood and infertility of resulting offspring, etc) almost all documented instances of spider-scorpion hybrids have been created in labs by artificial fertilization. (though it is funny to think about scientists sitting around a glass cage trying to encourage a reluctant scorpion to do a sexy little dance for his spider lady friend. you got this bro!)
Finally, it’s quite difficult to recognize a spider-scorpion in the wild, and even more difficult to verify its parentage without genetic testing. “Spider-Scorpion Hybrid” doesn’t refer to just one species or phenotype: appearances differs wildly based on parental species. And this is the most exciting thing about spider-scorpion hybrids: there’s no way to 100% predict what a new hybrid will look like before it hatches! Some have tails, some have pincers, some spin webs, and some do none of that but still manage to be terrifying!
And with over 45,000 known spider species and almost 2,000 scorpion species in existence (and more being discovered all the time) that makes *pulls out my high school graphing calculator*
Nature is fascinating and I hope you live in deep unease and suspicion for the short remainder of your days!

if jennifer of jennifer's body had just invested in some meal planning she could've stretched those dead boys into a week's worth of meals. that's why i'm so excited to announce the sponsor of this post, hello fresh. hello fresh is a meal delivery service that does the work of meal planning and meal prep for you, so you don't have to worry your pretty brunette head about figuring out where your next boy meal is coming from
NOTHING makes me more mad than people shoving aside creepy behavior just because the person in question is neurodivergent and doesn't pick up on social skills well. there was this girl in high school who got way too touchy with me no matter how many times I told her to stop and the fucking school guidance counselor and school psychologist were like "well you can't blame her because she can't pick up on social cues well". i'm neurodivergent too but if someone begs me to stop doing something it's kind of fucking clear they don't like it???
just the way people approach neurodivergency is so infantilizing I hate it. if you ever reblog a post about how it's ableist to react angrily to someone invading your space i'll fucking kill you. half the things you guys call ableism are just straight up not, and this isn't even a tumblr thing, it's something supposed medical professionals believe.
It's no longer a social cue if someone says "stop, i don't like that" it's literally just someone verbalizing what they expect you to do. which is stop.
feminism never taught me to hate men but it did help me realize that i shouldn’t prioritize them over women & it turns out that alot of men consider that to be hatred lmao.
So if you were in a room with two prisoners; a man and a woman, you’d never met, and the gender neutral soldier with the big gun told you to kill one of them, you’d automatically shoot the man?
