Many insect species overwinter in various rock shelters (cavities and crevices), but the microclimates of rock biotopes remain poorly understood. We investigated the temperature dynamics in rock microhabitats where clusters of egg masses of the wintering spongy moth L. (SM) were observed. Our research objective was to find the relation between the ovipositing behaviour of females and the landscape features in different parts of this species' range. Studies of the ecology of the SM are important from a practical point of view, as the moth causes significant economic damage to forests of the Holarctic. We found that the average monthly temperature of rock surfaces in the studied microhabitats was 2-5 °C above the average air temperature. More importantly, the minimum temperatures in these microhabitats were 4-13 °C higher than the minimum air temperature. These results help to reassess the role of the mountain landscape in the spread of insect species. Rock biotopes provided a significant improvement in the conditions for wintering insects. We believe that, when modelling the spread of invasive species (such as the SM), it is necessary to account for the influence of rock biotopes that may facilitate shifts in the northern boundaries of their range.
许多昆虫物种在各种岩石庇护所（洞穴和裂缝）中越冬，但岩石生物群落的微气候仍知之甚少。我们调查了观察到越冬海绵蛾卵块集群的岩石微生境中的温度动态。我们的研究目标是找出雌性产卵行为与该物种分布范围内不同地区景观特征之间的关系。从实际角度来看，对海绵蛾生态学的研究很重要，因为这种蛾对全北区的森林造成了重大经济损失。我们发现，所研究微生境中岩石表面的月平均温度比平均气温高2 - 5摄氏度。更重要的是，这些微生境中的最低温度比最低气温高4 - 13摄氏度。这些结果有助于重新评估山地景观在昆虫物种扩散中的作用。岩石生物群落显著改善了昆虫越冬的条件。我们认为，在对入侵物种（如海绵蛾）的扩散进行建模时，有必要考虑岩石生物群落可能对其分布范围北界移动产生促进作用的影响。
