We found the following beetle on July 1st, in Orem UT, at a public park among the wood chips. It was 7 p.m. at night and there were several of these beetles walking around the wood chips.
This is a male Stag Beetle in the genus Lucanus, but your location in Utah is a bit far west for the species we usually receive. We did some research on BugGuide, and we believe this is a Cottonwood Stag Beetle, Lucanus mazama, and if we are correct, this represents a new species for our website.
Wow thanks for getting back so soon.My five year old son is an avid bug lover and he thought it was great that he found these beetles. What’s funny is he insisted that they were a type of stag beetle, but we couldn’t find them on the web. It’s interesting you say they’re a bit far west because we saw between 20-30 in the playground. He’d like to know what they eat. Thank you for your info it’s been helpful.
Hi again Dante,
We should probably clarify what we meant by our “west” comment. Most of the North American Stag Beetle submissions we receive are from two species, the Reddish Brown Stag Beetle, Lucanus capreolus, and the Giant Stag Beetle, Lucanus elephus. The furthest west we know of for those two species is Texas. Your beetle is a different species, the Cottonwood Stag Beetle, Lucanus mazama, and BugGuide has only received submissions from Arizona and we have never received a submission of that species prior to your letter. You can try feeding your Stag Beetles overly ripe bananas or other very ripe fruit. Stag Beetles are believed to feed on tree sap, but there is not much available information that we are aware of regarding the feeding habits of Stag Beetles in the wild.
We are fascinated by the wood chip connection. We just located these reports from Europe (they have their own species there), that Stag Beetles are being found in places landscaped with wood chips. This is the best article we have read online in a very long time.
