Brownish Red Stag Beetle

Reddish-Brown Stag Beetle

Dear Jennifer,
This is a male Reddish-Brown Stag Beetle,
Lucanus capreolus, and it is the fourth submission of this species we have posted in just over a week.  We suspect it was attracted to your porch light.  According to BugGuide:  “Males use mandibles to fight at breeding sites.”
