A huge specimen with thick bands. In an earlier post I questioned whether they hunt smaller tiger beetles that share the same habitat (e.g., C. repanda, C. punctulata, C. scutellaris). I saw lots of C. formosa this spring in various sand and gravel pits near my house. This past weekend I watched one stalk and pounce on top of a C. scutellaris but then immediately break off the attack as soon as the smaller beetle flipped over and started to fight back! The formosa aren't the most graceful tiger beetles when it comes to take offs and landings. They are so massive that they frequently roll over a few times when they hit the ground.
