Atlas of the European Dragonflies and Damselflies
| General | • a medium-sized black-and-yellow species which is fairly common throughout Europe except the British Isles and the far north | |
| Classification | • suborder: Anisoptera (dragonflies); family: Gomphidae | |
| Conservation status | • IUCN Red List Europe: Least Concern (but ssp. albotibialis: Near Threatened) | |
| Scientific name | • Onychogomphus forcipatus (Linnaeus, 1758) | |
| Name genus | • Onychogomphus: from Grk. ὄνυξ (stem: ὀνυχ) = nail, claw, hook +; connecting vowel -ο-+; γόμφος = bolt, rivet, peg ⇒ for the shape of the male's lower appendage | |
| Name species | • forcipatus: from Lat. forcipatus, -a, -um = armed with pincers; [forceps = pincers] ⇒ for the shape of the male's appendages | |
| Distribution | • click or tap the Map button above | |
| Habitat | • rocky streams and rivers, but sometimes also at lakes | |
| Dimensions | • typical body length: 46-50 mm; hindwing: 25-30 mm | |
| Notes | • gomphids are 'sitters': they spend a lot of time perched on rocks and vegetation | |
| Both sexes | Head | ➤ like in all other gomphids, the eyes are widely separated |
| • the eyes are typically grey-green | ||
| ➤ there is a yellow bar on the black vortex | ||
| Thorax | ➤ the black lines on the side of the thorax are thin and wavy, leaving a wide antehumeral stripe, and they usually meet the mid-dorsal black stripe | |
| Male | Abdomen | ➤ there is a subterminal knob on the lower appendage |
| Photographs | • many of our photos below were made in Italy and Spain and show the subspecies O. f. unguiculatus | |
| • those photos made in Turkey show the subspecies O. f. albotibialis |

Onychogomphus forcipatus (left) and O. uncatus (right)
In O. forcipatus note the yellow bar on the vortex and the two black shoulder stripes which are both connected to the mid-dorsal black stripe.
Onychogomphus forcipatus (left) and O. uncatus (right), thorax
In O. uncatus the two black shoulder stripes are typically broad and parallel, while in O. forcipatus these stripes are thinner and wavier, and are both connected to the mid-dorsal black stripe.
