do insects feel pain?

A difficult question.\nThe two references below have something to say about whether or not fish feel pain. The arguement claiming 'Yes' is related to the evolution of survival behaviours and hard to refute. It does however hold true for any animal which responds negatively to stimuli.\nIt is certainly true that if you stick a pin into a maggot it will wriggle - it certainly does not like it. Fish are none too keen either.

cockroaches have exoskeletons

A quick question with a quick answer: They're not blind.\n\nBut if you're still curious if they use it to navigate around... No.\n\nThey use their hypersensitive antennae to navigate, distiguish objects, detect vibrations and find their food.\n\nA cockroach with its antennae cut off will die of starvation.\n\nI do this ALLLLLLLLLLL THE TIME!!!!\n\nAND ITS FEEEEEEEEELLS SO GOOOOOOOOD!!!\n\nYucky creepy bastards!

Tell us more. Do you know if you have been bitten by an insect? Is it red also I know it is difficult to see if in back but if you have a mirror maybe you could look. It could be a number of things but we need more information please.

Clearly, mosquitoes are the worst. What with all of their insipid blood sucking and what not. But what really creeps me out is when a gigantic bug flies onto you that you're not expecting, like a praying mantis or something. I'm really not feeling that action.

In my expert opinion, of looking at dead roaches for many..ah ...months, I have noticed that their legs curl up...it is hard to stay standing with yourself in the fetal position.  I know of know other reason, it seems if you even step on them, they at least roll onto their sides.

I'm not sure if they feel pain, but i do know that nature has designed their mouths to eat crawfish, other fish and lots of things that are prickly, pointed, sharp and hard. I don't think they would eat that stuff if it hurt.

It's all psychological and "anatomical (?):" When you hear something that's emotionally painful to you, your brain starts to think differently and asks and answers multiple questions at the same time, consciencely or subconsciencely. To some point of this simultaneous complex thinking, it will tell the tear ducts to expel tears for no reason. Also, it will have some kind of pain around your heart (the heart-break feeling).\n\nI don't know exactly why the brain does that, but I think it's merely psychological. All animals do not cry for emotional or physical pain (salt-water crocodiles "cry" to expel salt). My hypothesis would be that sometime millenias ago, crying was a sign of sadness in some way, then, as evolution takes place, it just becomes embedded in our mind that the instinct when we're in pain, we tend to cry. But that's just my hypothesis and to my extent of my knowledge.\n\nPS Penguins!!!

No insects sleep, in the traditional sense. They go into something called "diapause." What happens is at night in temperate climates, the air temperature drops to levels at which the insect can no longer function normally. They get sluggish, find a safe place to hide, and stay there, in a nearly "frozen" state, completely inactive until the sun rises and temperatures increase. \n\nFor ants in tropical climates, the air temperatures usually do not get chilly enough for them to go into diapause and they work throughout the night, never sleeping.\n\nSo the answer is true.

yes my dear insects have brain in the form of nerve complexes a network which seem to be like brain and what is the purpose of having a brain that is they are also organism every organism has need to think over its certain life time activities brain help them to coordinate their body with all parts and tell them abt all the physiological functions to be performed at different times

No, cockroaches have exoskeleton - meaning that the bones of theirs are on the outside.

Your intestines don't have nervous suppy for pain.  So, you can't feel your organs, but you can feel the inside of the tissues of your back, hence the pain is felt in the back.  It is usually a really deep low back ache.  Best wishes

No, but it probably feels vibrations, which is kinda like hearing.  Snakes don't have ears, but they "hear" vibrations.

when a bug bites you it injects a bit of its saliva and sometimes poison into your skin which causes itchyness so when you scratch any itch it feels better but try not to, it will keep the wound from healing because itching also means its healing and if you keep any wound open it is vulnerable to bacterias and infection.

Yeah I have read about that a lot of natural and alternative medicine books advocate this idea.Supposedly the insects not only bees are able to sense the deficiency and become threatened .

All insects including the cockroaches have what is known as an exoskeleton. This is like having an outter shell, kind of like a suit of shining armour...That is the best analogy I could come up with.\nThey do not have an internal skeleton like vertebrates do, in fact the exoskeleton is characteristic of all Arthropods, from the insects, to crabs and lobsters, to ticks, centipedes mites and scorpions.\n\nhope ths answers your question

i wouldn't worry about it.  when they bite, it only stings for an hour or two before the pain goes away.
