Vilken skam detta är. Så sitter politiker på sociala medier och gapar om hur enkelt och härligt det är att gå på bidrag i Sverige. svt.se/nyheter/lokalt/skane/…

Ever seen a many-plumed moth?
Alucitidae are recognised by their modified wings consisting of 6 rigid spines on each forewing and hindwing. Each spine is lined with flexible bristles, creating a structure similar to that of a bird's feather.
Look closer!
USA har, 20 år efter att Europa förstod, fortfarande inte förstått att förpackningsstorlek och blisterpack minskar risken för o/avsiktlig död rätt rejält.

this is an incredible comeback story for a beautiful and harmless insect that was nearly wiped off the earth forever by colonialism and you’re calling them “horrifying” fuck yall
