It's the time of year again for this pest

A potato beetle (latin: Leptinotarsa decemlineata), known for being a major pest of potato crops. Introduced in Europe in 1877. They are spreading since, expectations are that they will spread all over the world.
Usually I try to look where I tread, but so many cross my way, and remembering that, well, they are a pest, I, reluctantly, step on them.
