AbstractIn Odonates, female colour polymorphism is common and implies the presence of two or more female types with different colours and behaviours. To explain this phenomenon, several hypotheses have been proposed that consider morph frequency, population density, the presence of parasites, and mating behaviour. We studied the blue-tailed damselfly Ischnura elegans, a species with a blue androchrome morph and two gynochrome morphs (the common green infuscans, and the rare orange rufescens-obsoleta). The size of adult males and females, the presence of parasites, and pairing behaviour between males and the three female morphs was assessed in field conditions throughout the reproductive season in NW Italy. Moreover, growth and emergence success of larvae produced by the different morphs was analyzed in standardized conditions. In the field, males showed a preference for the gynochrome infuscans females, despite a similar frequency of androchrome females. In test conditions, male preference for the infuscans females was also observed. Paired males and paired androchrome females were larger than unpaired individuals, while there were no differences in size between paired and unpaired infuscans females. Males and androchrome females were more parasitized than infuscans females. The survival and emergence success of larvae produced by androchrome females was higher than those of offspring produced by the infuscans females. Our results suggest that a higher survival of progeny at the larval stage could counterbalance the higher parasitism and the lower pairing success of andromorph adult females and highlight the importance of considering the whole life-cycle in polymorphism studies.

AbstractIn Deinocerites, an aberrant offshoot of Culex, the larvae live in water in deep crab holes and the adults also are often found in the burrow. The males have elongate non-plumose antennae and specialized front claws, and often rest on the surface film. In observation cages the males associate with pupae (of either sex) at the surface of the water, hold them lightly with the claws and sense the pupal horns (spiracles) with their antennae. The male perceives the pupa at 1–2 cm. An emerging female elicits a strong response from males up to 15 cm. away; the males fight for possession and mating may be established before the female has fully emerged. The pupal skin continues to attract for several minutes thereafter. Emergence of the adult male was not successfully observed. Probably both pupal attendance and mating response depend on a chemical stimulus, which appears to be non-specific.The males also make slow exploratory flights near the cage walls, and a mating response may be elicited when their legs touch a resting insect. The response is made to either sex (perhaps more readily to the female) and again is non-specific. The two mating processes are presumably reinforcing, and both seem well adapted to the natural habitat provided the lack of specificity is tolerable.Several other mosquitoes, all of slow flight and restricted habitat, make similar irregular flights and mate on contact with resting females. Probably this behaviour represents the last phase of mating in more strongly flying (swarming) species, after the sexes are brought together by the auditory response mediated by the plumose antennae. In some mosquitoes the two patterns of behaviour coexist. Assembly at a swarm-marker and recognition in flight must be less necessary in non-dispersing forms in confined habitats, and most of all in Deinocerites. Several other crab hole mosquitoes show convergence or analogies with Deinocerites.The association with the pupa and the related attraction to the female at emergence find a parallel only in Opifex fuscus; but in Opifex these processes depend not on a chemical stimulus but mainly on vision, as befits an inhabitant of open sunlit pools.
