I think this is a stag beetle – I found it on my deck this morning. What do they eat and are they destructive? if there is one – can I assume there are more around? I live in Davidson County, Nashville, TN.

Reddish Brown Stag Beetle

Dear Rose,
This is a male Reddish Brown Stag Beetle,
Lucanus capreolus, and he is a magnificent creature.  According to BugGuide, adults feed on:  “Tree sap. Adults in captivity for study will readily drink diluted maple syrup or sugar water. Larvae feed in rotting logs. They are not harmful to vegetation.”  Stag Beetles can fly and they are attracted to lights, so this individual may have emerged some distance from your home.  Stag Beetles are not destructive.  They need rotting wood like stumps and logs to survive since the larvae take several years to mature.
