Almost all hunting insects have sharp eyesight, including the robber fly, it is the most deadly predator. The robber fly has several advantages in its hunting ability, one of which is the speed of movement even though the prey is still far away. This sharp movement makes the robber fly one of the most feared predators.
Look at the photo I got, a hunter fly managed to kill a stink bug. If you pay attention, you will see how its beak stabs right into the head of a stink bug. This means that the beak is very sharp and hard, something that can really be relied on.
Initially, I got a hunter fly that was relatively small and thin. When I was busy taking pictures of it, suddenly I saw a glimpse of a larger and more sturdy hunter fly, snatching its prey while flying. Just like an eagle snatching a chick and then taking it to its nest. And the robber fly has shot the stink bug's head without missing.
I'm going to put this (Head Shoot) into a daily #monomad contest organized and curated by
