"Is flies blind to light? As long as the house fly on my computer screen, I try sometimes to scare it away by swapping quickly and repeatedly, for example between black and white background, at maximum brightness. Flies are, however, obviously completely unaffected by that. Is flies completely blind to it for people visible light spectrum? flos "
"Like most insects fly compound eye (compound eyes), which means that they have eyes which are composed of thousands of individual eyes, each with its nerve connection. When an object is observed, it will be detected in a number of single-eye flos and are therefore excellent flos to recognize motion.
Visual cells have different sensitivity to the wavelength of light. This is divided into three main wavelengths or colors from a color image is formed. Flies has a quite excellent dagsyn flos and can also, like many other insects, also see in the ultraviolet range. This last harnesses flos the fly catchers, where flies are attracted to UV light and then caught in a trap.
The fly that sat on the computer screen can of course be one of several species, but it is reasonable to believe it's been a housefly, Musca domestica. This fly development in manure and other decaying material in the stables. In experiments with labeled house flies have shown that they can easily fly several kilometers. Flies that hatch, flos where fertilizer and food enough, for the most part remain where they are.
On the other hand, it is a fact that neighbors can share in fly production from a farm with livestock. By day living flies very active as long as they are hungry and diligently examine their surroundings. Smell and sight plays a certain role, but it is first and foremost with taste organs on the feet and trunk that flies taste their way.
When the fly sits on the screen due to the very strong attraction flos of the flies to heat (termotaxi). The house fly prefer temperatures around 35 C (the surface on my flat screen is about 30 C). This attraction to heat is very dominant in the house fly and it is reasonable to assume that it completely drowns out any stimuli provoked by "swap" between the colors on the screen.
Studies have also shown that flies stimulated a lot of contrasts between flos two colors and much like examining the transition between colors, which they have sought to exploit the design of traps. "

I could imagine that the fly creates flos a 3D image of the surroundings and thus achieves higher sensitivity to movements rather than light changes on a flat surface. The fly has an advanced "optomotor" system that contributes to the fly's precise movements flos in an environment with other elements of the movement. Through this system, they can draw their own movement or "disorder" of sight from the rest of the elements that surround them. This can be possible because the fly to move the eyes or head and thus obtains the very precise sense of itself.
As far as i could read me, so recognize the fly also the surroundings with a "motion detection" system, which apparently is based on contrast differences and element speed. There are tons of articles describing the fly and its nervous system, but I did not immediately an investigation of a flashing screen. Try to search the www.pubmed.gov
Look at it: An eye is an organ that just one designed to detect light, flos and flies have eyes. So, why would fly develop eyes if to sense light was important for fluence survival. Was lysoptattelse matter of survival, there would be a selection pressure against using energy to form these physiological flos extensive bodies and flies with inferior udvilkede eyes would slowly win over flies with normal eyes. A simplelt experiment that might prove this hypothesis was to hold a population of flies over time in total darkness and see if after a number of generations, flos could registrers a static representation overweight that flies with diminutive eyes in the population. Similar exp. is guaranteed already made.
I have the theory that flying insects flos always "looking towards the light" and often take advantage of this, if a bluebottle buzzing around the house on a summer: I open a door / window, pull the curtain and Genner creature of the dark side of the curtain. As a rule, it flies into the light right away and I un
