This beetle-like insect was found in a rotting osage orange in a riparian corridor of Brown County, OH on 11-04-07. As you can see in comparison to the fruit it is very small. My first thought was Carrion or Dung Beetle but they are much larger & almost endangered in this area. I’ve looked in all the most recent books & googled images & the only other similar looking sort of is the Pleasing Fungus Beetle. Attached are 3 images. What’s that bug?

Hi Mary Jo,
Your photo is lacking in detail, but it appears the abdomen of your specimen is protruding beyond the elytra or wing covers. This exposed abdomen signals it might be a Sap Feeding Beetle in the family Nitidulidae. There is a very close match on BugGuide, Glischrochilus fasciatus, commonly called the Picnic Beetle. According to BugGuide: “Adults found under bark of injured or dying trees, also come to sap, decaying fruit.” That is good enough for us to put our money on the ID.
