| ...mm. Their body shape resembles that of a bug from the genus Rhinocoris, but they are much smaller. The body colour varies from grey-brown to dark grey. The abdomen, however, is red in colour. The head of these insects is slightly round in shape. The distance between their eyes and the base of the antennae is about the same distance as between the eyes and the back of the head. The fourth segment of the antennae (which are always bent) is about the same length as the innermost antennal segment. | | |
| | ...ments of the antennae are black, the third is yellowish-brown. The 2nd segment is ovoid to roundish in shape. The area between the eyes is whitish-yellow or yellow and is broken up by a grey-yellow central line. The compound eyes are positioned at a distance to each other. In the males this distance is just wear slightly smaller. | | |

The black-lined skimmer is very shy and always maintains a greater flight distance. Females usually remain hidden in the riparian vegetation and only rarely appear. They hunt in the evening and can only be observed flying in daylight during the mating season. Mating starts in the air and is completed after 5 - 10 minutes on a soli... | | |
| | After mating, the females erect a cocoon for the eggs. The white cocoon is 6 - 7 mm in length and is hidden, at a slight distance from the hideout of the spider. After reaching maturity (after the last moult) the life expectancy of the males is very short, and most die shortly after mating. | | |
| | Mating takes place in summer and afterwards the male spiders live for a short time together with the females in the same web before they die. The females lay their eggs in a cocoon, hidden away and at a distance from the web. | | |
| | On the underside of the chest (thorax) are the defensive glands which emit an unpleasant-smelling secretion as a defense mechanism. This can be squirted over a distance of several decimetres. The abdomen is black at the edges (connexivum) and has yellowish-white markings. The side margins are densely dotted. The wing covers usually have dark brown patches of colour. Rhaphigaster nebulosa are clumsy fliers and buzz ... | | |
