The Malachiinae is a subfamily of beetles with orange structures along the sides of their abdomen. These structures can either be visible and sac-like or withdrawn and inconspicuous. The most common species in North America is the Collops quadrimaculatus, which is reddish in color with two bluish black spots on each wing cover. More information about the Malachiinae can be found on Fauna Europaea and Wikimedia Commons.
