I decapitated one of those big locust-looking grasshoppers in  in my garden last week. F*cker was still kicking a half an hour later. Usually I just knock them to the ground and stomp them, but this time I had pruning shears in my hand and just reached out and snipped its head off, right behind the two front legs and threw it in a bucket. When I went to empty the bucket later, the head and front legs were still wriggling and twitching, and the hind legs were still kicking and thrashing.

Was that gross enough for this thread?

Given that cockroaches are evil spawns of Satan, I fail to see how this is newsworthy.

Cockroaches are awesomely fascinating creatures. The fact that their nervous system is distributed along the entire body instead of being concentrated at the head is cool.

Headless cockroaches? That's nothing:

You don't need a head if you don't have a brain to support... Insects in general are kinda distributed-processing, their legs and eating bits and whatnot are all controlled by little knots of cells close to said parts.

One of the two more interesting things I've read in AI journals is how top-down approaches to multiple legs don't work, but if you just let each leg decide for itself, "ta-dah!" the problem simplifies itself immensely and starts to work.

The first most interesting to me was when I read how crickets could figure out direction with exactly 16 neurons. You had to have been there.

I was awoken one night by a scratching sound.  At first I was deeply worried because of horror films I've watched.  It is probably a natural inclination when one first awakens to strange stimuli.  Anyway, as my mind grew clearer, I was able to discern the general location from which the sound was emanating.  Thinking about the possible causes for the sound, I realized it had to be a large insect.  Waking up, getting some raid, I started moving things around and finally a huge as roach did make itself known.  I laid into it with the force of raid and it tried to resist, but no, raid proved its worth and soon the filthy creature slowed its fitful contortions and lay still.

And that is the story of my nighttime adventures against vermin.

Why there are two TV's in Oxaca:

Had just checked in to a hotel in Oaxaca, was wondering why they had two TV's. One on a stand, one on the dresser.

Then I saw the giant bug crawling across the dresserl Pure reflex, I picked up the TV and *BLAM* -squiiish-

Ok, I now know why that TV was there.

Imagine a very, very old world around a red-dwarf star puttering along in evolution about a bazillion years or so, and continuing long after we're gone.
Or just picture Australia's reefs.

Scientists have created simple RC cockroaches. They put an electrode at the base of both antennae, and turn it on briefly to trick the cockroach into thinking there is an obstacle there, so they turn away from it. Cockroach armies?... soon.

RoboRoach - now available as a DIY kit.

I wonder if there is a theoretical limit to how intelligent a species could become with distributed neural networks. A super-advanced alien race built like that would be that much more difficult to kill in the inevitable Space War.

Getting a kick out of this. Did undergrad research on differences in cockroach feeding habits based on sex.

It's not that a Roach head may be alive, or its body, that should disturb people. It's how narrow a female with a developed ootheca can get when it needs to squeeze somewhere.

Oh, and roach nursing. Oh, and those roach turds? Not all of them. Think broken roach penis- it's a violent, tricky act which starts with a gift of semen (assay the quality of the male and if high enough will provide nutrients for forming an ootheca).

Roaches are a fun topic. They're like our most important neighbors, well, next to the bacteria we need to live. Hahaha. Sweet dreams normies.

Roaches, fleas, and mosquitos. I fail to see the point.

Yeah. Sick farks. Gotta get kids into the "animal torture is fun" mode young.

How do the heads digest food without a body? I'm just asking questions here.

So, we were supposedly created to be the supreme beings on Earth, and here this lowly insect has far greater survival skills than we do.

I've read somewhere, that after a nuclear war or asteroid, insects will probably evolve from cockroaches, and birds from house sparrows. Don't know about mammals.
