EIn fact, no one wants a fight. Or so they say, winemakers and lepidopterists. But some things are offensive. For example, Lutz Hommes, a winemaker from Ernst an der Mosel, when the headlines read: “Are pesticides killing the rare Apollo butterfly on the Mosel?” Tomorrow says, “There's no evidence for that.” Leverkusen lepidopterist Tim Laußmann, on the other hand, is disturbed when the president of Mosel viticulture believes that his butterfly protection association has a “visible lack of competence”. Laußmann says: “Currently the climate is poisoned.” Apollo's butterfly is also poisoned in his eyes.

The butterfly is one of the particularly protected species. Federal states where it occurs must protect it from extinction. He lives on the Moselle river in open areas where wine grows, which attracts many tourists: on rocky steep slopes, where it is always a few degrees warmer and you can hardly get up without sensible shoes or a cog railway. Long gone are the days when grape growers sprayed their vines by hand. Since the 1970s, this has been done by a helicopter organized as a farmers' cooperative.
