Wood louse vs. Asian multi-colored lady beetle

Armadillidium vulgare / Harmonia axyridis


More carnage on our front door step! I wasn't aware that wood louse were predators but this guy was certainly chowing down on the lady beetle.

Thanks guys!
Nancy, yes, I think the ladybug was already deceased but I was still surprised as I thought that pill bugs were herbivores.

Roly-polys (woodlice) aren't predators but scavengers and largely herbivorous (

I never thought that two of my most favourite insects were into a duel!
Great capture!

Actually, I can almost guarantee you that the beetle was already dead (probably having been stepped on), and the pillbug is instead scavenging from the corpse.
Woodlice aren't predatory in the least, but are scavengers of dead and dying plant matter, fungi, and dead animals, so this is almost certainly just a case of carrion feeding by this arthropod.
