Contrasting population growth parameters of the aphidophagous Scymnus nubilus and the coccidophagous Nephus reunioni
TLDR
A significant difference in late survival was found, with S. nubilus exhibiting higher survival, and net reproductive rate, intrinsic rate of natural increase, and finite rate of increase were all significantly higher, and generation time and doubling time were both significantly shorter in S.nubilus compared to N. reunioni.
Prey life‐history influences the evolution of egg mass and indirectly reproductive investment in a group of free‐living insect predators
TLDR
It is suggested that ladybird predators of coccids lay smaller eggs because neonate larvae do not have to search, catch, and subdue prey, and both types of ladybirds have a similar reproductive investment relative to their body mass when phylogeny is controlled for.

TLDR
A slow-fast continuum in life history parameters and Theory of predator-prey interactions, which explains the rapid change in body size and foraging behaviour, are studied.
