Two rainforest butterflies have evolved to look more alike, likely to confuse shared predators. But why don’t they get confused themselves?
To avoid mating with the wrong species, they’ve cleverly evolved distinct scents.

Agreed! Though my backyard is on an arguably far-off land (which, nevertheless, does share some fauna/flora with less far-off lands).

Happy Halloween 🎃👻💀 from the crypt-keeper wasp, who lays its eggs into a crypt created by its host, then manipulates the host’s behavior for its own benefit, before devouring it from the inside out and emerging through its face!

The thing about entomology is, there are always weirder bugs than anything you could imagine on your own.
