A very surprised wife found this small beetle inside a folded-up sheet that had been hanging on a clothesline to dry earlier in the day. It seems closest to this image of Anomala orientalis. As it moved around actively inside the cup where I trapped it, often trying to fly out, many of the photos were blurry, but this one shows the markings on the wing covers clearly. Others showed how the antennae had a distinctive trifoil ending like the one in the linked specimen. I noticed that, as in this photo, that the beetle was constantly feeling the surface on which it crawled with these antennae. When I first trapped it, also, the insect held its long spiky hind legs up behind it in defense, much like the insect in the linked image.
