A predatory fly (Tolmerus atricapillus) often catches gnats and inserts its stinger to suck. Predatory flies are very agile hunters and often catch their pray in flight with their densely spiked legs. Their strategy is sit and wait, observe the airspace, attack at opportunity.

The hornet (Vespa crabro) often hunts honeybees and grashoppers. But they are not very selective about their food, using insects mainly as an additional protein source. Hornets are impressive insects, due to their size, but they are usually not agressive at all, except when the integrity of their nest gets threatened.

The european praying mantis is almost invisible in the vegetation, colors go from green to brown. If a prey comes into reach, they catch it with their spiked legs in a very fast grasping movement. Then they usually start to eat the head of the insect first, to prevent any further resistance. Praying mantises are old insects from a evolutionary perspective. Their nervous system is simple and they attack any moving objcet within a specific size range.

The red "murder bug" (Rhynocoris iracundus) lives up to its name and stabs a beetle (Rhagonycha fulva) and honeybee (below). Often, these bugs are in company of little black flies. These are, in the most cases, flies from the familiy of Milichidae. These flies are like vultures and wait for the large predators to kill an insect, from which they can then get their share of body liquid.
