Lepidoptera and UV range

good afternoon,
I immediately apologize for the number of inaccuracies that may be in this question, since I am a person far from entomology.

if I understand correctly, in butterflies, the part of the spectrum in which they see is shifted relative to ours towards the UV range, (as in birds (?)). and there are patterns in the UV range that butterflies see on top of each other (for example, determining gender), but we do not with our own eye.

have you ever seen works on this topic,
preferably in Russian or English,
or studied something similar yourself?

google gives me only brief essays, and a search on this forum did not give anything at all.

sorry again if the question is inaccurate or incorrect.

thanks

Butterflies have diverse vision, and many have color vision (in the visible part of the spectrum). Features of vision may differ not only in different species, but even (in some) within the same species (! sexual dimorphism in color vision). Vision in the UV range is characteristic of very many species of butterflies and plays a role in 1. distinguishing individuals of the opposite sex, 2. distinguishing specific patterns on flowers and nectar signs, 3. individuals of their own species from others by a specific wing pattern, which is distinguishable not only in the visible part of the spectrum, but also (details that are not visible to our eye) in UV. In vain many doubted here, this information is written in many SCIENTIFIC articles.
There are a lot of works, a lot of them are publicly available on the Internet, you just need to search well. But with rare exceptions, there are works in English and German. In Russian, too, there are, but in the public domain they are posted on the Internet a little.
