Do insects have feelings?
Karen Mesce, a neuroscientist at the University of Minnesota, points out that crustaceans—like insects—lack the nervous system structures that allow humans and vertebrates to feel pain. In humans, pain and fear are processed in the amygdala and the limbic cortex, which the brains of crustaceans and insects lack.
It is likely to lack key features such as 'distress', 'sadness', and other states that require the synthesis of emotion, memory and cognition. In other words, insects are unlikely to feel pain as we understand it.
Accordingly, bugs feel something like hunger and pain, and “perhaps very simple analogs of anger,” but no grief or jealousy. “They plan, but don't imagine,” Klein says. Even so, insects' highly distilled sense of self is a potential gift to the far-out study of consciousness.
No, despite some of the headlines that are spreading across the Internet, scientists have not found that flies are emotional beings, nor did they demonstrate that the insects experience feelings like fear in a similar way to us.
In Brief. Until recently, scientists thought that the ability to recognize individual faces required a large mammalian brain. But studies of paper wasps and honeybees have shown some small-brained insects can manage this feat, too.
As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.
In conclusion then, perhaps insects display base emotions but whether they feel love, grief, empathy, sympathy or sadness is unlikely. As humans we can feel and demonstrate kindness to an insect, it remains unknown if these emotions are ever reciprocated.
Insects can feel the basic needs of hunger, thirst, pain, danger, and “perhaps very simple analogs of anger,” and it is this basic thought-stimuli that drives them to act within their environments. This can be easily tested an observed through the selective actions of bugs.
Insects certainly display complex and apparently intelligent behavior. They navigate over long distances, find food, avoid predators, communicate, display courtship, care for their young, and so on. The complexity of their behavioral repertoire is comparable to any mammal.
In a paper published today in the Journal of Experimental Biology, researchers show for the first time that a social insect can form a drug dependency—a finding that they believe can help us better understand how addiction affects human communities.
Why do bugs love me so much?
Your blood type contains specific chemicals that may be very appealing to certain insects, especially mosquitoes, who can smell your blood right through your skin. Mosquitoes have been scientifically shown to prefer type O and A over other blood types. This is just another one of those things you cannot avoid.
Studies over the past century have discovered that many insects, like humans, acquire more than one type of spatial memory, that they acquire these memories at different rates and that, as they become more familiar with an environment, they change which memories they use.

In fact, there's mounting evidence that insects can experience a remarkable range of feelings. They can be literally buzzing with delight at pleasant surprises, or sink into depression when bad things happen that are out of their control.
But why does the housefly love you and your home? Houseflies LOVE the scent of food, garbage, feces, and other smelly things like your pet's food bowl. They're also attracted to your body if you have a layer of natural oils and salt or dead skin cells built up.
Here are some reasons why they land on humans: o They are attracted to carbon dioxide which human beings breathe out. o They are attracted to the heat of the warm body, to sweat and salt, and the more the person sweats the more flies they attract. o Flies feed on dead cells and open wounds.
By combining their normal head/eye movements - as they view the world in saccadic bursts - with the resulting light-induced microscopic photoreceptor cell twitching, the insects, such as flies, can resolve the world in much finer detail than was predicted by their compound eye structure, giving them hyperacute vision.
Scientists believe that insects sense vibrations in the air. They might have their vibration sensor in any part of their body: thorax, wing or legs. This organ is used to translate vibrations into nerve impulses that the insect will understand. Most importantly, insects can't hear when you tell them to leave.
“Ants, bees, and termites all have very high intelligence,” says Srour. “They have to recognize nest mates, communicate with them often.” The challenges of living within a large community require intelligence.
The short answer is yes, insects sleep. Like all animals with a central nervous system, their bodies require time to rest and restore. But not all bugs sleep the same. An insect's circadian rhythm – or the regular cycle of awake and asleep time – changes based on when it needs to eat.
Some researchers believe insects are terrifying mainly because their physical forms are so unlike our own — skeletons outside their bodies, a skittery way of moving, too many legs and too many eyes.
Can fishes feel pain?
A significant body of scientific evidence suggests that yes, fish can feel pain. Their complex nervous systems, as well as how they behave when injured, challenge long-held beliefs that fish can be treated without any real regard for their welfare.
'Most people would consider this as something very human to do, and now scientists find (personality) differences in all kinds of animals, even in insects,' said Dr von Merten, lead researcher on the EU-funded PERSONALIHI project, which looked at individual personality differences between shrews.
If she reciprocates his desire, they copulate. Shohat-Ophir previously found that for male flies, at least, mating is pleasurable. After sex, the insects' brains show an elevated level of a compound called neuropeptide F, or NPF -- a key chemical that's involved in its response to rewards like food and sex.
Insects also have a rudimentary sense of ego, though very different from Narcissus or Kanye. Instead, it's the ability to act on certain environmental cues and ignore others. “They don't pay attention to all sensory input equally,” Barron tells Viegas.
Many insects communicate to defend themselves either with warnings to potential predators, or to scare away threats. They will also communicate to attract a mate of the same species.
