👉 Isotomidae are a family of insects in the order Coleoptera, which includes bees and wasps. They are characterized by having a single abdominal segment (anothorium) that is divided into two segments: the first segment is called the abdomen and the second segment is called the thorax. Isotomidae have a long, slender body with a large number of legs and wings, which help them in their foraging and pollination activities.
