What's That Bug? does not endorse extermination

Leap Day Posting UpdateJust as we decided to to change the status of this posting, we realized another possibility.  Might Rhinoceros Beetles hibernate if they don’t mate or if they emerge late in the season?

Hi, I just found these beetles in the rotted out center of an old (100+ yrs.) dead red oak tree stump in New Market, Virginia. I was mixing dirt into the compost-like material when I found them. Their bodies are appx. 2 1/2 inches long. At first I thought I was looking at a bug with vertical pinchers but then I realized that only the bottom one moved. They have two smaller “horns” on either side of the large one. I think their eyes are down near where the lower pincher meets the body. Can you tell me anything about these beetles?

Dear Steve,
What a marvelous discovery you have made.  These are male Eastern Hercules Beetles,
Dynastes tityus, the heaviest species of beetle found in North America.  Immature grubs are found in rotting wood.  Adults normally appear in summer, with most sightings occurring in July.  We are guessing that unusual weather is causing emergence schedules of insects to change.  We suspect these two guys completed metamorphosis and perhaps they are waiting for ideal conditions to emerge from the rotting stump to mate and reproduce.
