Insect behavior and intelligence

I'm not saying insects have a particularly spectacular
memory or complex emotions or anything, but after spending
quite a bit of time with some praying mantises I found in
Hungary, I have found that their responses to external
stimuli are more varied and advanced than most books I've
read on insects let on. Even though it's all instinctual,
the way a praying mantis will, for example, shift it's prey
from two hands into one and attempt to catch another insect
with it's other limb, finish the first, and then move on the
second, is quite impressive to behold. And there's lots more
little things they do which are always overlooked. The same
can be said for what I'm feeding them on - crickets - which
freeze as soon as the predator's head shifts towards them,
gang up on predators if there is enough of them (from all
directions, as if it were planned), and do lots of other
nifty things. I know there's a danger of applying more
meaning or intelligence to a behavior than is actually going
on, but the sorts of things I'm noticing repeat enough for
it to be more than coincidence.

I don't know why I felt the urge to share that here. Perhaps
it's because this absurd obsession is a bit embarrassing to
discuss in the 'real world'...

how do spiders know how to make webs?

how ...do flies know how to fly like jet fighter pilots just
1 day out of the thing they come from!?

why does it take a human so long to know how to do anything
!?

insects are by far more impressive and creepy because of it.

you astound me freqy

there's a great section in godel, escher, bach on ant
colonies, he reckons once they reach a certain size they
behave similarly to a single conscious entity.

Ants astounded me too. There's lots of larger wood ants over
there, which build large mounds out of twigs, bits of earth,
anything. I watched ants struggle to drag a dead insect
alone, give up, walk about a bit in a confused, drunken
manner, then bump into two or three others and return to
carry the dead creature with their aid. Then the dead thing
gets dragged by all of them towards the hole, where two
larger ants stand on guard and wave their heads up and down
towards the others a bit, as it to say, "oh, you're ok, go
ahead and take that down." And all over the shop, they're
doing things like that, carrying bits here, cutting bits
down into smaller bits there, dropping things and going back
to them with others.

def. check the godel,escher bach book. there's A LOT covered
in it. and in a brilliant way. for example when explaining
emerging 'intelligent' behavior of an ant colony, like horse
mentioned. reading the whole book is like graduating in
artificial intelligence. almost all aspects of ai are
covered.

yet...the man is saying god is remote controlling the ants
from above? or that he installed the intelligence into
there minds ?
or that ants are like an efficient considerate respectful
version of us humans?

it seems the ants are born with information ...or instinct
...yet the whole thing is working as one ....kinda like a
human body thing...if i didnt have a kidney i would die if
ididnt have a heart i would die...this ant thing is like a
body but outside crawling around.



im not sure's.

Hah... well, unfortunately I can't excuse this obsession by
blaming it on the use of drugs. I'm sure if you found a
praying mantis, you'd give up all earthly pleasures in a
quest to serve him/her/it and discover it/her/him's deepest
secrets. They're very interesting.

I'm always blown away by the things insects manage to
accomplish with only rudimentary nervous systems. I've heard
about the cricket behavior you mentioned, but have never
seen it. The idea of a synchronized cricket assault is
strangely terrifying! I'm interested to learn of any other
mantis or cricket behaviors that you observed repeating -
this stuff fascinates me. I'm glad you had the urge to share
this, it's the most interesting thread I've found here in
weeks.

Thanks to everyone who suggested the related books, I'll
definitely have to look into them.

Drunken Mastah: what do drugs have to do with this?

Oh, thanks.

I've been collecting/observing a few kinds of insects for a
few years, and I've seen all these little behaviours that
aren't ever discussed in books and articles (or are
simplified - female mantises, for example, do not just eat
the male's head after mating as a matter of ritual, but
simply try and kill and consume the male as a prey like an
other if he fails to escape her back post-sex without her
seeing him). Since you're interested, I'll gladly list a
bunch of observations a bit later. :-)

*as a prey like any other

Also, normally she gets through more than just the head of
the male. Most failed escapes I've seen result in the poor
bastard being eaten in his entirety. If she's already fat
enough, though, she won't manage more than the head and
neck.

I don't like the insect world, there is no humanity there,
no good things at all. EAT EAT EAT.
I'm sure everyone here saw that life in the undergrowth
thing with those social spiders that have a huge web that
stretches for miles (i think i dunno). If something lands in
it then spiders nearby asses it's eatabilty then pluck the
web to send a signal that makes thousands of the fuckers
come down on the helpless prey. The cold efficiency of
that...I can't help but hate it even if it fascinates me. I
know that is nothing compared to things like ants and shit.

well we should respect them still ampi, cus they have been
here longer than us, and some of them do serve a purpose.
for example spiders are good in your home, because they eat
other little insects which you don't want.

Did you know that a fruit fly cell contains 13,601 genes.
Human cells, by contrast, are thought to have more 70,000
genes and fruit flies share nearly 60% of human genes

Oh yeah, like some sort of amount of time ago, I was
'outside' and there was a small board of wood on the ground
that I wanted to move, so I just picked it up and moved it
but it kinda scraped the ground. Well I looked and I totally
scraped off like half of this earwig's head on accident and
it was still alive and stumbling around in agony. I watched
in horror as ants later came by to harass and kill it
slowly. So if I didn't exist maybe it would still be alive
and happy today. Is my life worth the life of that earwig,
no, it is worth much much less (and also I killed this
spider that was in my house recently because it was too hard
to capture it with a cup to let it outside). True story.

By the time I read godel escher bach, none of it was new to
me at all. I read that information in previous better books
that didn't annoy me with poems about turtles between every
chapter. HOFFsteaEadeer's singularity talk was one of the
stupidest ones too, not that I have any brain wiring for
talking myself. If I ever find myself in a position where I
have to talk to someone I better close my eyes and imagine a
keyboard and see if I can somehow type the syllables.

ants and bees have more complex social structures than most
mammals.

a complex social structure isn't necessarily a sign of
intelligence, however.

I'll start a list of random little things I've noticed with
the mantises :-)

-Unless they're preoccupied with climbing, when you walk
into a room they'll often swivel their heads towards you and
follow your movements with their head across the room. After
a while, once it's established you're neither a threat nor
prey, I assume, they stop doing this and do whatever they
were doing before.

-I don't know where this idea that mantises lie in wait for
prey came from, really. They do remain completely still if
no other creatures are nearby, but they can see other things
from quite far away and I've often seen them stalk and then
run after other insects over large if they're hungry enough.
They can loose interest if an insect is smart enough to stop
moving, though, though that's rare.

-The way they clean themselves is cool. They'll nibble their
front legs and wipe their face after with them, in exactly
the same way a cat will lick its paws and wipe its face.
They'll sometimes proceed to grab their back legs or antenna
with their front and pull them towards their mouth to clean
- it looks a lot more impressive than it sounds. They'll
only clean if they're settled down.

- If you spray water or drop water on them, they will try
and use their two front legs to pick up a droplet and bring
it to their mouth. If there's a droplet on their face, for
example, they'll swipe their face (like they do when they
clean themselves) and drink off their front claws. If a
droplet dribbles under their mouth (on their neck), they can
swivel their head down at an award angles and suck it from
below their heads. If they have wings and water is on them,
they'll flutter them to flick it off, and may go on to bend
down to drink flicked water off surfaces around them
(although they'll do that anyway if water is around.)

-Talking of wings, they can hiss by rubbing their abdomens
against their wings in a certain way, and will flare their
wings up (like a fan opening) if something approaches that
is bigger than the

*If something approaches that is bigger than them. This is
most exciting when two full grown females meet head on;
they'll look at each other, then both will begin to flare up
their wings, hiss, and then strike each other with their
front legs. One strikes the other, and then the other
strikes back, back and forth, until one backs off or runs
away. However, many times when I used to introduce females
(I don't do this any more) one would end up eating the
other, even if they were equal in size, because it observed
the other walking from behind. For a strange ritualistic
fight to occur, normally one female has to walk head on
towards another female; however, if one female happens to
notice another walking from a distance, she may often not
engage in a fight but simply try and grab the entire other
female like it was a regular cricket or anything else. The
other female will attack back and may cause damage or even
free itself (because of its equal size), but often, because
it has been grabbed by each claw at opposite ends of its
body, it can't do very much in defense (when mantises
capture things like wasps and other insects with dangerous
defenses, they'll hold each end of the creature, stopping it
from either stinging or biting, and start eating alive from
the middle (or anywhere where there isn't a sting or
mandibles.)
Males don't seem to engage in fights or attack other males;
they're much smaller, more nervous, and need much less to
eat.

That's it for now, but there's loads more little things I've
seen. Hope it's not too boring for ya, Zephyr Twin . :)

awesome... I'd love to have a large terrarium furnished with
real plants and such for a pet praying mantis.. They've been
my favorite insect since I was a child.

In regards to mantises lying in ambush vs. stalking prey on
open ground, I've heard that the orchid mantises are the
ones that ambush prey, as their bodies have evolved to look
exactly like the flower which gives them their name.

That's true, I've never seen orchids stalk, or leaf
mantises. I wouldn't personally recommend these to own,
though, as they seem to be very fragile breeds (unless I was
just unlucky with the ones I got.) Orchid mantises are
beautiful, though. :-)

kinda like most western kids are into dinosaurs.

I found a praying mantis outside my apartment yesterday. I
wanted to catch the bugger but he was all big and creepy and
doing sign language with his hands.

Bees are pretty cool too. they behave in similar social
manner as ants but its all controlled by chemical secretions
