Clubtails and Hooktails (Gomphidae)
Species
These dragonflies form part of the Gomphidae family, which contains about 90 genera and 900 species worldwide. They are commonly referred to as clubtail dragonflies. The name refers to the clublike widening of the end of the abdomen (abdominal segments 7 through 9). However, this club is usually less pronounced in females and is entirely absent in some species. One Gomphus, one Ophiogomphus, seven Onychogompus and one Paragomphus species are found in Europe.
