Do Japanese Beetles Bite?
Japanese Beetle Biology
While Japanese beetles do have robust mandibles (teeth) they use to chew leaves, their teeth are too weak to break through skin and they do not bite people.
However, adult Japanese beetles do possess stout spines on their legs that can cause skin prickliness, which people may perceive to be a bite
So why is there content on the Internet that describes Japanese beetles as biters? The writers may be confusing Japanese beetles with Asian lady beetles.
Asian Lady Beetle Bites
Asian lady beetles deliver a mild bite when they come in contact with exposed skin.
People bitten by Asian lady beetles describe the bite as feeling like a mild pinprick. However, the bites are of minor consequence since the beetles rarely penetrate the skin.
