She's a female heavy jumper. She was actually a killer hidden behind that adorable face. You may also refer to it as a "little killer." She only kills when she is hungry, thus she didn't kill for no reason.
For lunch, she was successful in killing a housefly. The prey was held in a tight grip, and not moving at all. She was unconcerned with the prey's agonizing fight to the death. She had to eat since, after all, she was hungry.
The main character in this picture is a heavy jumper, so the object of her prey is purposefully blurred. But that's not the underlying cause. Only the main character, the heavy jumper is plainly apparent because it was focused with an extreme macro lens. These pictures were intended to be included in the daily #monomad challenge.
