“…Insects of most species, however, live at a much finer spatial scales than conceived even by these models. There is evidence that even within these buffering microhabitats (grasslands, forests), finer scale patches show great thermal heterogeneity, including plant surfaces that are sometimes warmer than ambient air temperature [45,61,62].…”

“…Such measurements are relatively easier when the microhabitat does not receive direct solar radiation, like for spiders living in subterranean caves [63]. Otherwise, measurements with high spatial and temporal resolutions are required [62]. (ii) A renewed focus on behavioral mechanisms by which insects respond to and exploit the vast thermal heterogeneity that often is available to them [7].…”

Climate warming impacts biological systems profoundly. Climatologists deliver predictions about warming amplitude at coarse scales. Nevertheless, insects are small, and it remains unclear how much of the warming at coarse scales appears in the microclimates where they live. We propose a simple method for determining the pertinent spatial scale of insect microclimates. Recent studies have quantified the ability of forest understory to buffer thermal extremes, but these microclimates typically are characterized at spatial scales much larger than those determined by our method. Indeed, recent evidence supports the idea that insects can be thermally adapted even to fine scale microclimatic patterns, which can be highly variable. Finally, we discuss how microhabitat surfaces may buffer or magnify the amplitude of climate warming.

“…Therefore, the temperature of the microclimate should be considered to better comprehend the global response of insects to environmental temperature variations. Yet, the microclimatic temperature to which most animals and plants are exposed remains to be quantified (Lembrechts et al, 2020;Pincebourde and Sallé, 2020;Pincebourde and Woods, 2020). Some species build structures for diverse functions during part or all of their life cycle.…”

Temperature strongly drives physiological and ecological processes in ectotherms. While many species rely on behavioural thermoregulation to avoid thermal extremes, others build structures (nests) that confer a shelter against climate variability and extremes. However, the microclimate inside nests remains unknown for most insects. We investigated the thermal environment inside the nest of a temperate winter-developing insect species, the pine processionary moth (PPM), Thaumetopoea pityocampa. Gregarious larvae collectively build a silken nest at the beginning of the cold season. We tested the hypothesis that it provides a warmer microenvironment to larvae. First, we monitored temperature inside different types of nests varying in the number of larvae inside. Overall, nest temperature was positively correlated to global radiation and air temperature. At noon, when global radiation was maximal, nest temperature exceeded air temperature by up to 11.2-16.5°C depending on nest type. In addition, thermal gradients of amplitude from 6.85 to 15.5°C were observed within nests, the upper part being the warmest.Second, we developed a biophysical model to predict temperature inside PPM nests based on heat transfer equations and to explain this important temperature excess. A simple model version accurately predicted experimental measurements, confirming that nest temperature is driven mainly by radiation load. Finally, the model showed that nest temperature increases at the same rate as air temperature change. We conclude that some pest insects already live in warm microclimates by building their own sheltering nest. This effect should be considered when studying the impact of climate change on phenology and distribution.

“…Finally, it also provides a step forward towards accurate predictions of future microclimate (Lembrechts & Nijs, 2020). Note however that the proposed approach is suitable for those organisms living on, in and around the soil surface (e.g., soil micro‐organisms like fungi, ground arthropods, herbs, mosses, tree seedlings and small vertebrates), yet does not cover more peculiar habitats like those of invertebrates living under the bark of a tree, or parasites living in the fur of a mammal (Pincebourde & Salle, 2020).…”

Issue Climate change, and its impacts on ecological, agricultural and other societal systems, is most often studied by relying on temperature data derived from countrywide weather‐station networks. Yet, these data do not capture microclimates, those arising from soil, vegetation and topography, at spatial scales relevant to the majority of organisms on Earth. We argue that a unified strategy is missing to design regional or countrywide networks to measure microclimates and thus provide ecologically relevant and sound climate data, for instance for modelling biodiversity and ecosystem functions. Evidence Here, we develop an integrative framework to design effective microclimate networks for potential implementation at the country level. With the dawn of novel low‐cost sensor technologies and modelling techniques it is time for designing standardized microclimate networks. We make an important step forward in that regard by providing hands‐on training to generate an optimal sensor distribution to capture as much microclimate diversity as possible at the regional or country scale. Conclusions By implementing our framework to design countrywide or regional microclimate networks, strategically positioned to capture a representative picture of microclimates available within the focal country or region, governments could lay the foundation for the development of a next generation of modelling and synthesis of landscapes, to serve a range of societal needs now and into the future as climate change accelerates.
