|Bibio clavipes belong to the genus Bibio, in the order two winged flies (Diptera), the suborder Nematocera, the infraorder Bibionomorpha, the superfamily Bibionoidea and the family bibionids (Bibionidae). Scientific synonyms for Bibio clavipes are: Bibio dorsalis, Bibio flavicollis, Bibio tancrei and Hirtea ephippium. This species of Bibionidae is widespread in Europe and is found en masse in coniferous forests. |
|The Bibio marci is the most frequently occurring member of the family Bibionidae. Bibio marci are widespread in Europe and Asia. They belong to the order Diptera and are encountered? are common? from March on, swarming out frequently around 25 April.
Bibio marci are black and shiny. Their bodies can reach a length of 8 to 11 mm. They are similar to flies but are the biggest kind of Bibionidae in Europe. Sometimes they appear in large swarms on shrubs and small plants. Bibio marci love to be in the proximity of water and in open landscapes.|
|Bibio marci have relatively short antennae (9 sections ). Females and males can be easily differentiated by their eyes. . The males have hemispherical shaped eyes, while the female's eyes are small and on the side of the head. The females are smaller than...|
... are smaller than the males. The males typically let their legs hang down in flight and are rough and hairy. The females are predominantly smooth. The wings of the females appear black, the wings of the males, white.
The main food source of the Bibio marci are different plant juices, nectar and sometimes pollen. Bibio marci like living in bushes, shrubs or on small plants.
|The life span of Bibio clavipes is very short. This species is one of the few bibionids, which are active in September. Bibio clavipes feed on nectar and honeydew and do not sting.
Bibio clavipes reproduce once a year. During mating season, partners come together in large swarms. Fertilization of the females starts in the air and is completed on the ground. |

...ry large, and have compound eyes of various dimensions on the upper side of the head which is hairy (the face too), while the females are smaller and hairless. The females have a spike to dig with on their forelegs. The colour of the male and female Bibionidae is different, the male being black and the female being reddish brown to amber. In spring and autumn Bibionidae often swarm en masse. They do not sting and they feed on nectar or honeydew. They contribute to the pollination of fruit trees. The insects mate within the swarm, and the males of the Bibio marci for example can become very aggressive. While the Nematocera are generally good flyers, i. e. the Bibio hortulanus are sluggish and slow.
The female Bibionidae lay up to 3, 000 eggs, individually or in small groups in the soil, where they are buried. The hatched larvae, which are resist to the cold, are usually hairy and are found en masse (especially in the upper layers of humus). They live on rottin...
...e soil, where they are buried. The hatched larvae, which are resist to the cold, are usually hairy and are found en masse (especially in the upper layers of humus). They live on rotting plant remains and are important soil regenerators. The pupae of Bibionidae also live in the soil. The larvae can be harmful when they occur en masse especially in times of drought as they also attack the roots of living plants.
