Multicolored Asian Lady Beetle – Harmonia axyridis (Pallas) – “Halloween Ladybug”
A bit of a pest in my estimation, they are everywhere in October. They have displaced the native ladybugs. They are beneficial because they eat aphids, but are a bit disgusting for home owners. They nip just enough to be felt, gather in every crevice in your house, and reflexively bleed a smelly liquid.
