Increased fecundity, as a function of multiple mating, in an arctiid moth, Utetheisa ornatrix
@article{LaMunyon1997IncreasedFA, title={Increased fecundity, as a function of multiple mating, in an arctiid moth, Utetheisa ornatrix}, author={Craig W. LaMunyon}, journal={Ecological Entomology}, year={1997}, volume={22} }
1. Female Utetheisa ornatrix mate multiply and may receive up to thirteen spermatophores. Spermatophores provide the female not only with sperm but also with a nuptial gift of pyrrolizidine alkaloid that she transmits to the eggs, protecting them against predation. Thus, through multiple mating the female accrues nuptial gifts that add to the defence of her offspring.

Male indifference to female traits in an arctiid moth (Utetheisa ornatrix)

Abstract. 1. Female Utetheisa ornatrix (Lepidoptera: Arctiidae) mate selectively with large males able to transmit sizeable quantities of nutrient and defensive pyrrolizidine alkaloid with the…
Parental Body Mass as a Determinant of Egg Size and Egg Output in an Arctiid Moth (Utetheisa ornatrix)

It is demonstrated that mating with larger males results in accelerated oviposition by the female on the day after mating and that females are intrinsically prone to lay larger eggs in the first days after mating.
Female Promiscuity Does Not Lead to Increased Fertility or Fecundity in an Arctiid Moth (Utetheisa ornatrix)
- BiologyJournal of Insect Behavior

Evidence is shown that U. ornatrix females are not taking multiple mates as fertilization insurance because females that mate once are as fertile as those that mate three times; and females that take three different mates are no more fertile than those that mates three times with the same male.
Female choice increases offspring fitness in an arctiid moth (Utetheisa ornatrix).

It is shown that eggs sired by larger males are less vulnerable to predation, whereas sons and daughters, by virtue of being larger, are, respectively, more successful in courtship and more fecund.

It is reported that body mass is heritable in both sexes, indicating that by choosing larger males females obtain genetic benefits for their offspring by exercising mate choice female Utetheisa.
Apportionment of nuptial alkaloidal gifts by a multiply-mated female moth (Utetheisa ornatrix): eggs individually receive alkaloid from more than one male source

It is shown that individual eggs may receive PAs from more than one male source and that individual males have no assurance that the PA they themselves contribute to the female will find its way exclusively to eggs of their siring.

In permanent pairs, remating increased female fecundity and fertility but suboptimally fed females benefited more from remating, while mass-reared pairs had a lower remating frequency.
Precopulatory assessment of male quality in an arctiid moth (Utetheisa ornatrix): hydroxydanaidal is the only criterion of choice
- BiologyBehavioral Ecology and Sociobiology
- 2001
Females of the moth Utetheisa ornatrix mate preferentially with males that excel in three quantitatively correlated attributes: body mass, systemic content of defensive pyrrolizidine alkaloid, and glandular content of the courtship pheromone hydroxydanaidal.

If male-provided benefits (prezygotic or otherwise) are more costly than female costs of offspring production, reproductively-ready males will act as resources limiting female reproduction.
