Shifting Baseline Syndrom. Eins der großen Probleme in der Wahrnehmung des Artensterbens. Kurz gesagt: Das was wir als Heranwachsender kennen, wird als der Normalzustand empfunden.

This insect is a female Giant Ichneumon Wasp, specifically the species Megarhyssa atrata (also known as the Black Giant Ichneumon Wasp).

This is the Eight Circled Cross page from the Book of Kells. The level of detail is absolutely insane; I made a replica of this a couple of years ago, and even scaling it up to twice the size, there were still sections I had to simplify because the detail was just too fine.
