Koloradka originally was tsarist Russia reward. Later it was revived by soviets in WW2, but not used much after the war. Then Putin revived it as a symbol of continuous history of tsarist Russian empire, USSR and his regime. Nowadays it's a symbol of modern Russian imperialism with a historical flavor.

In those parts of europe where both tsarist Russia and Soviet union were occupiers and now Putin is a threat, koloradka is pretty much on the same rank as nazi symbols.
