Germany's Biting Insects: Mosquito Look‑Alikes and Grass Mites

In Germany, skin reactions often blamed on mosquito bites can actually be caused by a range of biting insects. Horseflies (Tabanidae) cut the skin with scissor‑like mouthparts and lap up the blood, while black flies (Simuliidae) rasp the skin before feeding. Tiny biting midges of the Ceratopogonidae family also make shallow wounds to draw blood. These insects employ a feeding method called telmophagy, distinct from the piercing action of true mosquitoes.

A separate but related problem is the seasonal surge of grass mites (Neotrombicula autumnalis) in Berlin and surrounding areas. The microscopic larvae climb onto grass blades and latch onto humans, creating small abrasions that release a irritating secretion. The resulting red, itchy papules often appear hours after exposure and can last for weeks. The bites are harmless and do not transmit disease, but scratching can lead to infection. Prevention includes prompt showering after outdoor activity, washing clothes at high temperature, and keeping grass short through regular mowing.
