          The life-like fidelity of organisms captured in amber is unique among all kinds of fossilization and represents an invaluable source for different fields of palaeontological and biological research. One of the most challenging aspects in amber research is the study of traits related to behaviour. Here, indirect evidence for pheromone-mediated mating behaviour is recorded from a biting midge (Ceratopogonidae) in 54 million-year-old Indian amber. Camptopterohelea odora n. sp. exhibits a complex, pocket shaped structure on the wings, which resembles the wing folds of certain moth flies (Diptera: Psychodidae) and scent organs that are only known from butterflies and moths (Lepidoptera) so far. Our studies suggests that pheromone releasing structures on the wings have evolved independently in biting midges and might be much more widespread in fossil as well as modern insects than known so far.

          Mating systems of blood-feeding flies.

           Boaz Yuval (2005)
          The mating system of each species is a unique, dynamic suite of interactions between the sexes. In this review I describe these interactions in the families of flies that contain blood-feeding species. A transition from the aerial swarm, with rapid copulae and no direct female choice, to substrate-based systems with lengthy copulae and opportunities for female choice is evident at both a phylogenetic scale and within nematoceran families under specific ecological conditions. Female monogamy is associated with the former, polyandry with the latter. I suggest that the intensity of sexual selection operating on males in systems where the probability of mating is low has favored male ability to control female receptivity. Reproductive success of males is universally correlated to successful foraging for sugar or blood and (in some species and ecological conditions) to body size. Understanding the ecological basis of the mating systems of these flies will help formulate integrative, sustainable, and biologically lucid approaches for their control.
