I found this insect inside of my shoe. It is approximately 1cm in length and less than half a centimetre wide. It was found in the Netherlands, in the province Gelderland.
What kind of insect is that?
As @fileunderwater suggested: the question is "close" but not identical. I think that the suggested duplicate will only provide an identification of the family of the insect, but nothing more precise and specific. Therefore, the answers for the 2 questions vary.
