Sex and reproduction lie at the heart of studies of insect behavior. We begin by providing a brief overview of insect anatomy and physiology, followed by an introduction to the overarching themes of parental investment, sexual selection, and mating systems. We then take a sequential approach to illustrate the diversity of phenomena and concepts behind insect reproductive behavior from pre-copulatory mate signalling through copulatory sperm transfer, mating positions, and sexual conflict, to post-copulatory sperm competition, and cryptic female choice. We provide an overview of the evolutionary mechanisms driving reproductive behavior. These events are linked by the economic defendability of mates or resources, and how these are allocated in each sex. Under the framework of economic defendability, the reader can better understand how sexual antagonistic behaviors arise as the result of competing optimal fitness strategies between males and females.

Dimorphic Expression

The dimorphic expression of body size, body – head size relationships, and chromatic characters among anguid lizards is reviewed. These characteristics are quantitatively examined in a population of Barisia monticola. No sexual differences are found in body size. Head size is positively correlated with body size; however, allometric growth rates in head size are significantly greater in adult males than in females or juveniles. Adult males also differ significantly in eight of nine chromatic characters, the most pronounced being the presence of light dorsal scale markings. These differences are explored in the context of both natural and sexual selection. We hypothesize that the absence of dimorphism in overall body size is the result of natural selection operating to maximize female reproductive potential. In contrast, we predict that dimorphism expressed in body – head size relationships and dichromatism are consequences of sexual selection relating to agonistic and reproductive behavior of males.

Following long-term investigations of over 50 amphibian populations in the Republic of Moldova and Italy, the ecological and evolutionary peculiarities of reproductive behavior in some species of the orders Caudata and Anura were elucidated. For the first time, at the autecological and synecological level, the evaluation of amphibian nuptial systems - parental input, reproductive success, “r” and “K” reproductive strategies and their role in the evolution of sexual selection and the realization of the reproduction potential as a fundamental mechanism for the survival of amphibian populations in various environmental conditions was emphasized.

Following from long investigations of more than 50 populations of amphibians from the Republic of Moldova and Italy were elucidated ecological particularities and evolutionary reproductive behavior of some species of Caudata and Anura Orders. For the first time, on Autecological & Sinecological level, has been made assessment of nuptial systems of amphibians – of parental contribution, reproductive success, „r” & „K” reproductive strategies and their role in sexual selection and evolution the attainment of reproductive potential as a fundamental mechanism of survival of amphibian populations in various ambient conditions.

Diverse Groups

Although Anomalochrysa maclachlani shares many aspects of its life history and reproductive behavior with other green lacewings, it is atypical in several respects. (i) The preoviposition period is long, and it remains constant at temperatures from 21 through 26.7 °C. (ii) Fertility, which was 100% at 23.4 °C or lower, drops to 16.6% at 26.7 °C. (iii) Females oviposit clusters of about 25 unstalked eggs every 1–7 days, (iv) Both sexes produce loud clicking sounds during courtship; clicking frequently occurs in duet and is associated with anterior-directed flicks of the wings, (v) Females and males may mate repeatedly within several hours. The unusual features of A. maclachlani's reproductive behavior suggest a mode of sexual selection different from that in other chrysopids. Its loud courtship songs and those of other Hawaiian insects (Drosophila, crickets, plant hoppers) represent striking cases of parallel evolution among diverse groups of endemic fauna.
