Temnothorax nylanderi is a low-key species of ant found mostly in Europe, where it builds nests in tree bark and rotting branches and other woody, secluded places. This tiny brown arthropod leads a quiet life, preferring shade and shelter and staying out of the way of the woodpecker’s bill.
But for all this quiet, T. nylanderi faces a strange, alien threat in the form of a parasite that turns its members into yellowed, sedentary oafs. These compromised individuals hang out in the nest, not doing much of anything, defying what it means to be an ant.
