Species of long-horned beetles, true bugs, even aphids who imbibe at the milkweed bar, all wear these warning colors proudly.

So the team of scientists tested 373 different invertebrates—isopods, flies, centipedes, spiders, beetles, slugs, locusts, true bugs, and others—for nematodes.

Fungi, beetles, true bugs, mites, butterflies and moths showed clear movements to higher latitudes, whereas viruses and nematode worms shifted to lower latitudes.
