Question 1

True or false: Stag beetles are venomous and can deliver a painful, medically significant bite to humans.

Accepted Answer

False. They lack venom glands. Males can pinch with their mandibles, but it's not venomous and rarely breaks human skin.

Question 2

True or false: Stag beetles are named for their mandibles that resemble the antlers of a male stag (deer).

Accepted Answer

True. Their large, branched mandibles look strikingly similar to deer antlers, which is why they're called 'stag' beetles.

Question 3

True or false: Female stag beetles have significantly smaller mandibles than males and are rarely seen above ground.

Accepted Answer

True. Females possess much smaller, functional mandibles for chewing bark, and they spend most of their time underground laying eggs.

Question 4

True or false: Some stag beetle species can fly, despite their large and heavy-looking bodies.

Accepted Answer

True. Many species have functional wings beneath their hard wing cases and fly clumsily at dusk, often attracted to lights.

Question 5

True or false: Male stag beetles use their large mandibles primarily for digging and feeding on wood.

Accepted Answer

False. Males use their oversized mandibles to fight other males over territory and mates, not for digging or feeding on solid wood.

Question 6

True or false: Stag beetle larvae take several years to develop, often living in rotting wood underground.

Accepted Answer

True. Larvae can spend up to 5–7 years underground feeding on decaying wood before pupating into adults with a short lifespan.

Question 7

True or false: Stag beetles primarily feed on live tree sap and are major agricultural pests worldwide.

Accepted Answer

False. Adults drink tree sap but don't damage healthy trees. Larvae eat only dead, rotting wood, so they're decomposers, not pests.

Question 8

True or false: In Japan, stag beetles are kept as pets and can be found in vending machines.

Accepted Answer

True. They're popular pets in Japan, especially among children, and live beetles are sometimes sold in specialized vending machines.
