For ever and ever: When the wedding flight never ends
Date:1/7/2011

rofessor Dr. Rolf Beutel of the University Jena explains. Until today the placement of Strepsiptera in the phylogenetic tree of insects remained an enigma. "The females of these strange animals are almost always endoparasitic, i. e. live inside their hosts", Beutel continues. However, according to Beutel, the females of the analyzed species must have been free living. This conclusion is based on the simple shape of the external genitalia of the Mengea male. The males of species with females parasitizing in winged insects always have an anchor-shaped penis. "This firmly connects the males with the females, which are embedded in fast moving hosts such as for instance plant hoppers or bees." This specific docking mechanism is clearly missing in Mengea.

Moreover, the Jena research team could confirm the position of the extinct Mengea within the evolutionary tree. "These are ancestral predecessors of strepsipteran species existing today", says Dr. Pohl. Finding females and copulating was the only mission of the males during their extremely short life span. "This is clearly reflected by their anatomy", says the insect researcher. Highly efficient antennal sense organs and 'raspberry eyes' help to track the female. The flight apparatus and the genitalia were particularly well developed. In contrast to this, the mouth parts and the digestive tract are distinctly reduced compared to other insects. "The males were not able to ingest food, at least not in solid form", Professor Beutel concludes. It is possible that the intestine was filled with air, which improves the flying capacity of these tiny insects.

The Jena researchers will scan more amber insects in the near future. "This method has an enormous potential", Dr. Pohl says confidently. It not only allows a very detailed study of external and internal structures but is also non- destructive, in contrast to other techniques. Both aspects combined will guarantee an immense progres
