Current knowledge on less investigated factors, such as selection mediated by natural enemies, genetic drift and gene flow, environmental constraints, phylogenetic inertia, or biochemical constraints that could be invoked to explain scent variation are reviewed.

The results are incompatible with negative frequency-dependent selection, a hypothesis invoked to explain colour polymorphism in other rewardless orchids, and several hypotheses to explain the maintenance of white morphs in O. mascula are proposed.

The chemistry and the morphology of the androconia reinforce the current classification of the Castniidae in the Cossoid/Sesioid assemblage and provide new information on the chemical ecology in day-flying Lepidoptera and suit the recent paper describing the courtship behaviour.

To understand the cues involved in mating behavior and the role of male scents in male mating success, sequences of P. archon courtship behavior were quantified using video filming and the possible roles of male scent emission in female mate choice are discussed.

It is hypothesized that colour variation plays the key role in pollinator attraction, and that white-flowered individuals may be regarded to function as “sensory traps” in Orchis mascula, and it is proposed that the maintenance of white-Flowered mutants in O. mascula may result through kin selection, in which they act as helpers increasing the reproductive success of related purple individuals.

It is proposed that potential variations in pollinator species abundance or diversity and the co-occurrence of nectar-producing species in the community may have driven the adaptation of each variety to its current pollination niche.

The case of Orchis mascula, a deceptive orchid species in which the presence of rare white-flowered individuals is known to increase the percentage pollination of co-occurring coloured morphs, is investigated and kin selection is favoured as the means by which floral colour polymorphism is maintained in this species.
