“…On the other hand, the positive correlation found in the core population between mass and wing aspect ratio exhibits an opposite form of selection on the physical characteristic of the individuals, overall, influencing less the flight parameters. Finally, the lower thorax–abdomen ratio observed in butterflies from the edge population appears counter‐intuitive, as it is usually related to a lower flight performance (Chang et al., 2021; Langellotto et al., 2000). This relatively smaller thorax (as well as their overall smaller size) may be a side effect of a faster development (Neu & Fischer, 2022), and may help individuals from the edge population to cope with suboptimal resources (smaller individuals having lower energetic requirements).…”

Natural range shifts offer the opportunity to study the phenotypic and genetic changes contributing to colonization success. The recent range shift of the Southern small white butterfly (Pieris mannii) from the South to the North of Europe offers a prime example to examine a potential dispersal syndrome in range‐expanding individuals. We compared butterflies from the core and edge populations using a multimodal approach addressing behavioral, physiological, and morphological traits related to dispersal capacity. Relative to individuals from the core range (France), individuals from the edge (Germany) showed a higher capacity and motivation to fly, and a higher flight metabolic rate. They were also smaller, which may enhance their flight maneuverability and help them cope with limited resource availability, thereby increasing their settlement success in novel environments. Altogether, the behavioral, physiological, and morphological differences observed between core and edge populations in P. mannii suggest the existence of a dispersal syndrome in range‐expanding individuals. Whether these differences result from genetic and/or phenotypic responses remains, however, to be determined.

“…Our study species has high fecundity and a short generation time compared to most vertebrates but is not particularly extreme for an invertebrate. There is a general trade‐off between fecundity and vagility in grasshoppers, and in insects more generally due to the costs of building and maintaining flight muscles (Chang et al., 2021; Tigreros & Davidowitz, 2019). Thus, it may be that many insects threatened due to their limited colonizing ability are inherently of high fecundity and hence more amenable to translocation.…”

Translocation is an increasingly used tool in conservation management, but there is a risk that source populations are overcollected. The risk depends critically on the detection probability and the source population size. We quantified this risk for a wingless grasshopper population in a patch of remnant habitat in suburban Melbourne that was condemned to be cleared for housing development. We collected ∼2000 grasshoppers in five samples spread over 1 month and used the results to estimate the initial population size (∼300) with high confidence. Despite our perception of substantially depleting the population, we removed only an estimated 60%, and this relatively high fecundity (∼50 eggs per lifetime) annual species had recovered by the following year to near its original density. Wild‐to‐wild translocation is likely to be a low‐cost and effective strategy in the conservation of many invertebrates, and our findings highlight the feasibility of using natural source populations.

“…Body size (a proxy for fat reserves, because size and fat content are generally correlated in arthropods; Enriquez et al, 2022 ; Lease & Wolf, 2011 ), longevity, and reproductive output are common life history traits for assessing fitness in insects (Roff, 2001 ). Trade‐offs between longevity and dispersal (e.g., flight), as well as longevity and reproduction have been well documented (Blacher et al, 2017 ; Chang et al, 2021 ), where fat allocation underpins both trade‐offs. The tight relationship between fat reserves and fitness thus makes the study of fat accumulation of importance for both ecological and evolutionary studies.…”

The parasitoid Leptopilina heterotoma has been used as a model system for more than 70 years, contributing greatly to diverse research areas in ecology and evolution. Here, we synthesized the large body of work on L. heterotoma with the aim to identify new research avenues that could be of interest also for researchers studying other parasitoids and insects. We start our review with a description of typical L. heterotoma characteristics, as well as that of the higher taxonomic groups to which this species belongs. We then continue discussing host suitability and immunity, foraging behaviors, as well as fat accumulation and life histories. We subsequently shift our focus towards parasitoid‐parasitoid interactions, including L. heterotoma coexistence within the larger guild of Drosophila parasitoids, chemical communication, as well as mating and population structuring. We conclude our review by highlighting the assets of L. heterotoma as a model system, including its intermediate life history syndromes, the ease of observing and collecting natural hosts and wasps, as well as recent genomic advances.
