“…Whitney and Johnson (2005) showed that increasing the nighttime temperature increased the intrinsic rate of growth in Pieris rapae [48]. The effects of nighttime temperatures on the adult lifespan of the Finnish Glanville fritillary butterfly (Melitaea cinxia) [49] were similar with this study. The larval and pupal survival was only significantly affected by the highest daytime temperature.…”

The Fall Armyworm, Spodoptera frugiperda (Lepidoptera, Noctuidae), is a serious migratory pest. After invading China in 2019, the species was established as a year-round breeding population in most of the southern provinces. The area of winter maize in this region has been increasing due to the huge demand of fresh maize consumption, which is potentially at risk from this invasive pest, although the growth and development of S. frugiperda in the region’s changing climate is unclear, particularly with rising temperatures at night. Here, we used the highest daytime temperatures of 27 °C, 24 °C, 20 °C and decreased these by 2, 4 and 6 °C to reflect the range of nighttime temperatures indicative of winter conditions in a warming climate to evaluate the effect of increasing night temperatures on the growth and development of S. frugiperda. Results show that the survival of larvae and pupae significantly declined with daytime temperatures declining and the nighttime temperature range increasing. Significant developmental effects were observed across all daytime–nighttime temperature treatments, except for adults. Additionally, there were significant interaction effects for all stages, except the egg stage, and generation time. The development rate increased with the increasing daytime temperatures and nighttime temperatures, except for the intermediate treatments (Group II). The uniformity of pupation and emergence times were higher under high daytime temperatures and nighttime temperature treatments. Predictions of FAW development and warnings to local farmers need to be adjusted to take into account the more rapid development when nighttime temperatures increase in the warming climate. These results will support decision makers in developing long-term management strategies for FAW in southern China.

In recent decades, climatic change has grown to one of the most concerned problems in the society. Species across the globe have been responding to climate change. In this article, butterflies responses across the globe towards climate change are mainly focused on. But-terflies are sensitive to climate change due to their species interaction, high mobility and links with specific habitat conditions. They also have a wide distribution, covering all con-tinents but Antarctica. Climate change impacts biodiversity and affect butterflies various behaviors. This article has discussed butterflies organismal responses, range shifts, altera-tions of phenology behaviors and species interaction. After analyzing studied data, it is shown that climate change has led the genetic revolution of certain mountain butterfly spe-cies to extinction. Warming climate has increased voltinism in European butterflies and has created mismatches in trophic interaction via driving mountain butterflies towards the summits. It is also studied in the article that warming night temperatures effect oviposition and life span of Finnish Glanville fritillary butterflies. The effect of disturbed El Nino/La Nina frequency due to climate change on tropic butterfly abundance has also been men-tioned. Climate change has also affected monarch migration and population via shifting host plant distributions. By diving deep into the specific response butterflies have towards climate change, a more developed view on the effects of climate change could be gained. This is aimed for finding solutions to better preserve biodiversity.

“…Thus, it is important to account for food consumption when determining plasticity in life-history strategies, which may be one of the animals' key defences against ongoing environmental change [20][21][22]. Warming influences resource allocation patterns across animal taxa [23][24][25]-yet, the combined and potentially opposing effects of heatwave exposure and predation risk on life-history strategy are poorly understood.…”

Hot and scared: how do heatwaves and predation risk impact resource acquisition and allocation?

Heatwaves are increasingly prevalent and can constrain investment into important life-history traits. In addition to heatwaves, animals regularly encounter threats from other organisms in their environments, such as predators. The combination of these two environmental factors introduces a decision-making conflict—heat exposure requires more food intake to fuel investment into fitness-related traits, but foraging in the presence of predators increases the threat of mortality. Thus, we used female variable field crickets ( Gryllus lineaticeps ) to investigate the effects of heatwaves in conjunction with predation risk (exposed food and water sources, and exposure to scent from black widow spiders, Latrodectus hesperus ) on resource acquisition (food intake) and allocation (investment into ovarian and somatic tissues). A simulated heatwave increased food intake and the allocation of resources to reproductive investment. Crickets exposed to high predation risk reduced food intake, but they were able to maintain reproductive investment at an expense to investment into somatic tissue. Thus, heatwaves and predation risk deprioritized investment into self-maintenance, which may impair key physiological processes. This study is an important step towards understanding the ecology of fear in a warming world.
