We had a ton of these bugs in our garden once upon a time. I think they got introduced through some plant we bought and in the absence of natural predators, they just multiplied profusely. We had so many in the garden once upon a time that they would be found basically everywhere. You move something or pick up a leaf and you find these critters running around. They move pretty fast and look more interesting than scary with their yellow spots looking like racing stripes. But since our garden became so infested with these critters we had to get them eradicated with pesticide. Harmless creatures that curl up into a ball when touched.

the yellow spotted millipede is very common in the Pacific North West
is is an organic composter, it eats decayed plant materials
curls up in a ball for defense like a sow bug, it also secretes cyanide compounds to defend itself, smells like almond extract. be careful when handling
