This may be because while running, the beetle is moving too fast for its visual system to accurately process images. To avoid obstacles while running they hold their antennae rigidly and directly in front of them to mechanically sense their environment. The oldest fossil tiger beetle yet found, "Cretotetracha grandis", comes from
