To the question of vision

They see and distinguish a lot of things. Social hymenoptera, for example, can distinguish many colors and shapes of objects. There is a lot of literature on this subject - read the classic works of Frisch, Masokhin-Porshnyakov ("Insect Vision"). From foreign colleagues - R. Menzel, T. Collett, M. Shrinivasan, L. Chittka. Yes, many more people, these are the first who came to mind. The topic is very extensive.

Thank
you I have the Masokhin-Porshnyakov book, but what is frisch? in principle even fabre has many examples of how well image differentiation works in insects

Karl von Frisch-won the Nobel Prize for his discovery of the bee dance. Randolf Menzel-his student, he has very interesting articles on vision and memory.

More Frantsevich look for

Hawk moth has very good color and object vision. Plus the ability to learn. I fed the butterflies directly from my mouth.

Bees, not known as wasps, may also have visible light from yellow to ultraviolet, red does not differ

I'm also interested in the subject of insect vision, especially mosquitoes. If anyone has any information on this issue, please share.
I'm looking for the spectral sensitivity curves of mosquito light receivers, but I can't find them, bees and flies are described, but there are no mosquitoes. Maybe someone knows how many light receivers a mosquito has and what are the wavelengths of their maximum sensitivity?

Maybe of course the answers are in these books:

but I don't have these books. Tell me where you can find them!

The visual organs are represented by complex faceted eyes (giving a direct and mosaic image) and simple eyes. Insects distinguish the shape and color of objects

Praying mantises can pick out movement, but they can also pick out corpses if they want to eat. They can distinguish an aggressive attack from a simple movement. they see very small objects and can see people in the distance. Or feel it? Who knows how mantises see?

- In my yard, a male C-beloe anglwing, sitting on a post, took off and chased several times after taking off from him at a distance of 5 m!!! a red-brown pigeon!... - But this is understandable, based on the proportional projection of the visible size of the object...

Many horses began to run away when the distance from me to them was about 4-5 m.
And dragonflies are downright amazing, from a few meters you can distinguish small, fast-flying insects...

I had to observe how sitting on the flowers of yarrow Lebia cruxminor when approaching them began to quickly run away at a distance of 2.5-3 m.

Ktyri flies are simply analogous to falcons in the insect world in terms of visual acuity and ability to catch prey. I had to observe in the south of Kazakhstan how the ktyri Stenopogon avus caught Moroccan locusts and Turanian prus in flight, it seems to sit quietly, and once-already sucks the prey. They ran away from me from a distance of 3-3. 5 m. I had to try my best to catch them.

Lepidoptera have complex faceted eyes or simple ocelli.One butterfly can have 2 faceted eyes and 2 simple ones.Butterflies have color vision,but some colors may not be perceived by individual butterfly species at all.Lepidoptera perceive moving objects better.

I read about the good eyesight of ktyri, but for some reason I didn't notice it myself. They can see well, since they catch insects in flight, but I've hardly ever seen them fly away from me. I often caught them and photographed them, but somehow they didn't notice the danger. I don't know, maybe I get the wrong species, maybe something else. Maybe I'm not the only one, someone also noticed it.
