It differs by species; some have to find their next host almost immediately, but many have an egg stage that can lie in wait for days, months, or years!
Nope, you would definitely suffer much worse, and even when you’re hungry, your intestines still certainly have plenty of nutrients in them for a tapeworm to absorb. Basically you would just be speeding up what it’s already doing to you.
Nope! Not that anyone’s aware of yet, anyway.
If you mean bites or stings, I’ve only ever had one bumblebee sting and one yellow jacket sting, both from accidentally stepping on one barefoot in the grass.
Once they’ve softened up the innards of their prey with their venomous fangs, they sort of “slurp” through a tiny, muscular hole, as far as I know, but some will also sort of “chew” with the chelicerae.
Unfortunately to this day I have never, ever found an actual clear image of a spider’s mouth-hole. Even professionals I’ve spoken to can only provide a vague description.
They fly here, but it’s not as obvious. They prefer to fly at night, and preferably when it’s warm out!
Basically, whatever works. Theirs are very simple hearts laid out in a chain along much of their front half. In insects, the heart is a tube all the way down their back from nearly the brain to the butt. The single, big, concentrated heart of us vertebrates is fairly unusual in the animal kingdom.
How do other people know so much about video games or movies? :)
If you like something, information about it just sticks.
Flatworms such as planarians can survive being cut into small pieces and grow back, but earthworms actually can’t; their severed halves only live for a little while longer. They’re complicated animals with brains, multiple hearts and a nervous system that doesn’t regenerate as easily as the ultra-simplified flatworms.
Yeah, larvae are a stage in a “complete” metamorphosis, and also tend to have simpler anatomy than just a nymph stage like in a dragonfly or a true bug :)
