The Effect of Flexible Growth Rates on Optimal Sizes and Development Times in a Seasonal Environment
The study focuses on the optimal responses of size, development time, and growth rate to changes in the amount of time available for completion of the life cycle, and shows that the optimal growth rate and size at maturity may respond in several different ways.
Proximate Causes of Rensch’s Rule: Does Sexual Size Dimorphism in Arthropods Result from Sex Differences in Development Time?
This study found only a weak positive relationship between SSD and SBM overall, suggesting that growth rate differences between the sexes are more important than development time differences in proximately mediating SSD in a wide but by no means comprehensive range of arthropod taxa.
Monandry and polyandry as alternative lifestyles in a butterfly
The possibility that the trade-off between degree of polyandry and life span when singly mated may affect the maintenance of genetic variability in female mating frequency in this species is discussed.
Sex-related variation in growth rate as a result of selection for large size and protandry in a bivoltine butterfly, Pieris napi
Rearing larvae at the critical daylength, a two-way ANOVA on growth rate shows that there is an interaction between sex and developmental pathway in a polyandrous and bivoltine butterfly, Pieris napi.
Polyandry and its effect on female reproduction in the green-veined white butterfly (Pieris napi L.)
Although the nutrient investment of the first male to mate with a female “subsidizes” the progeny of later-mating males, the male nuptial gift in P. napi clearly qualifies as both paternal investment and mating effort.
Mass and production rate of ejaculates in relation to monandry/polyandry in butterflies
The results showed that not only is the mass of the ejaculate greater in more polyandrous species, but also the rate at which males are able to produce sperm and accessory substances is greater, indicating that sperm competition is important for explaining variation in ejaculate mass in butterflies.
Seasonal butterfly design: morphological plasticity among three developmental pathways relative to sex, flight and thermoregulation
The results suggest sex‐related, adaptive seasonal plasticity for morphological traits related to flight behaviour in a multivoltine insect.
Egg-laying patterns in butterflies in relation to their phenology and the visual apparency and abundance of their host plants

Among the Swedish satyrids, two of the three species which do deposit their eggs on the larval hosts overwinter in the pupal stage, thus necessitating rapid larval development, and butterflies which use visually apparent host plants seem to find their host plants without having to alight on non-hosts, whereas butterflies that use hosts that are visually non-apparent frequently alight in the oviposition search before they find the appropriate plants.
Adaptive variation in growth rate: life history costs and consequences in the speckled wood butterfly,Pararge aegeria
It is argued that for the understanding of life history variation it is necessary to consider not only the two dimensions of age and size, but also to take into full account the triangular nature of the relationship between size, time and growth rate.
