Excentricus planicornis are widespread from Western and Central Europe to southern Scandinavia and North Africa. In Germany, this species is common. The size of the current population is difficult to gauge, because this species is not sufficiently discovered. In Bavaria, the species is accepted as at risk. In the "Red List" (a list of endangered species) of Bavaria.

Female Excentricus planicornis reach body lengths of 4.9 - 5.5 mm and are therefore slightly larger than the males, which are 4.6 - 5.3 mm in length. The body is slenderly built and tapers into a point at the end of the abdomen.

The antennae are black. An important characteristic of this species is the remarkably large and wide 2nd segment, which is about five times longer than it is broad. The 3rd and 4th segments are thready and thin. The 3rd segment is bright yellow at its base. The 4th and outermost antennal segment is of a yellow-black colour. The eyes are large and reddish-brown. The scutellum, which is about as long as it is wide, is also of note. The wings have curved outer edges, are black in colour.
Excentricus planicornis are often found on ruderal plants, especially herbs, deciduous trees or shrubs. Adults can be encountered from June to October. They prey on aphids, psyllids, tortrix moth caterpillars, ermine caterpillars and other arthropods. Occasionally, they also eat plant parts (berries, buds etc.).
After mating, the fertilized females lay their eggs on plants. The eggs overwinter. The larvae which hatch in late April, are also predatory. Excentricus planicornis are considered useful as they destroy many plant pests and are especially appreciated in orchards.
