Swallowtail butterfly

I could not immediately find a good translation for "Koninginnepage".
Swallowtail butterfly I find a bit of a strange translation but well there is nothing else.

In the mountains around the lake, I found many of these rare butterflies for the Netherlands.

In the extra picture I captured a wasp or fly that I could not identify. It is I believe no wasp because I could not immediately see an angel, but a fly with only four yellow spots on its body I could not find too. Strange!
