I am searching for an identification for the group of bettles in the enclosed photo. They have gathered in a sap pocket of an American Elm Tree in Eastern Colorado.
It is difficult to make out the details of the individuals in your photo, but we nonetheless believe they are Sap Feeding Beetles in the family Nitidulidae, possibly Glischrochilus quadrisignatus, the 4-Spotted Sap Beetle which is pictured on BugGuide.
