“…Ectotherms, such as insects and other arthropods, are particularly sensitive to temperature and, thus, should be good indicators of the effects of climate change (Buckley, 2022). However, the large‐scale effects of climate and land use change across insect populations are poorly known and have been widely debated (e.g., Dornelas & Daskalova, 2020; Wagner et al, 2021).…”

Climate change models often assume similar responses to temperatures across the range of a species, but local adaptation or phenotypic plasticity can lead plants and animals to respond differently to temperature in different parts of their range. To date, there have been few tests of this assumption at the scale of continents, so it is unclear if this is a large‐scale problem. Here, we examined the assumption that insect taxa show similar responses to temperature at 96 sites in grassy habitats across North America. We sampled insects with Malaise traps during 2019–2021 (N = 1041 samples) and examined the biomass of insects in relation to temperature and time of season. Our samples mostly contained Diptera (33%), Lepidoptera (19%), Hymenoptera (18%), and Coleoptera (10%). We found strong regional differences in the phenology of insects and their response to temperature, even within the same taxonomic group, habitat type, and time of season. For example, the biomass of nematoceran flies increased across the season in the central part of the continent, but it only showed a small increase in the Northeast and a seasonal decline in the Southeast and West. At a smaller scale, insect biomass at different traps operating on the same days was correlated up to ~75 km apart. Large‐scale geographic and phenological variation in insect biomass and abundance has not been studied well, and it is a major source of controversy in previous analyses of insect declines that have aggregated studies from different locations and time periods. Our study illustrates that large‐scale predictions about changes in insect populations, and their causes, will need to incorporate regional and taxonomic differences in the response to temperature.

“…Temperature-dependent development models permit the examination of the impacts of temperature on the local occurrence, geographic distribution, population dynamics, dormancy, overwintering, and management of insects and mites [ 30 , 31 , 32 ]. Knowledge of the performance of predators and parasitoids in natural and applied biological control at various temperature regimes is highly relevant in order to develop forecasting models and find the natural enemies that best-match with the environmental conditions of the target pests [ 33 , 34 ].…”

The development rate of the predatory ladybird, Stethorus gilvifrons (Mulsant), fed on Tetranychus urticae Koch, was determined at 15, 20, 25, 27, 30, 34, and 38 °C. The total development time from egg to adult emergence for females was estimated to be 61.4, 31.6, 14.4, 13.3, 12.5, and 11.7 days, respectively. The development time decreased with increasing temperature from 15 to 34 °C, but all eggs failed to hatch at 38 °C. The lower temperature threshold (T0) for the entire development period and the thermal constant (K) for female S. gilvifrons were estimated to be 11.64 °C and 194.50 degree-days (DD) using the common linear model, and 11.96 °C and 187.87 DD using the Ikemoto and Takai model, respectively. Data were fitted to 20 non-linear development rate models and the thermal thresholds (Tmin and Tmax) and optimal temperature (Topt) were estimated. Among non-linear models, the Briere-2 and Ikemoto and Takai linear model provided adequate descriptions of the temperature-dependent development of S. gilvifrons. The upper-temperature threshold was estimated to be about 44 °C using the Logan-10 non-linear model. The estimated thermal development characteristics can be used to predict the occurrence and the population dynamics, as well as to improve the mass rearing and release, of S. gilvifrons for the biological control of T. urticae.

“…Meanwhile, the hostparasitoid interaction could be kept intact as parasitoids seem to be following their hosts (families of predators and pollinators). We do suspect that the different responses of arthropod taxa to climate in this study could reflect their life history strategies (Buckley, 2022;Gallinat et al, 2015). As temperatures rise, the growth rate of insects increase (Chaves et al, 2015), and univoltine insects, that dominate in the Arctic (Høye et al, 2020), are therefore expected to advance their fall senescence.…”

“…Univoltine species tend to advance and shorten their phenology compared to multivoltine species that often delay their late season phenology (Glazaczow et al, 2016). Temperature sensitivity among species can also explain differential phenological responses (Buckley, 2022;Thackeray et al, 2016), where early active species advance their spring emergence and late active species delay their fall activity (Bartomeus et al, 2011;Brooks et al, 2017;Gallinat et al, 2015;Kharouba et al, 2014). Furthermore, differences in phenological responses can be associated with greater sensitivity to environmental cues that are not affected by climate change, such as photoperiod (Bale et al, 2002;Danks, 2007).…”

Arthropods respond to climate change by shifting their phenology in the spring and summer seasons. These phenological shifts are rarely uniform, and taxa show distinct variation in the direction and magnitude of phenological responses to climate drivers. To gain insights into the most climate-sensitive taxa and forecast the implications of climate change on community-wide activity and biotic interactions, it is important to understand how the climate affects the timing of activity of different taxa in local sites within a community. Here, we examined the temporal trends of arthropod phenology, and associations between arthropod phenological responses and climate predictors using arthropod monitoring data from five different habitats in high-Arctic Greenland covering a 25-year period. We found that, for most taxa, advanced arthropod phenology was associated with earlier snowmelt, and, to a lesser extent, warmer temperatures. However, the magnitude of advanced activity varied considerably between arthropod taxa and local habitats. Our study also revealed that pollinators were the most climate-sensitive group, with advanced and, in some habitats, shortened seasonal activities. Late active taxa and late snow melting habitats advanced phenology at greater magnitudes than early active taxa and early snow melting habitats. The magnitude of phenological shifts of arthropod taxa was dependent on habitat, highlighting the substantial spatial variation in phenological responses. Overall, our results demonstrate that high-Arctic arthropods are capable of tracking local climate drivers of phenology well, but the phenological responses of arthropod taxa to global climate change are complex, and community-wide trends may mask the variation in direction and magnitude of phenological shifts in different taxa and locally adapted populations.
