There is an increasing volume of literature on the impact of climate change on insects. However, there is an urgent need for more empirical research on underrepresented groups in key areas, including species for which the effects of climatic change may seem less evident. The present paper illustrates the results of a study on a common forest tenebrionid beetle, (Piller and Mitterpacher, 1783), at a regional scale within the Mediterranean basin. Using a large set of records from Latium (central Italy), changes in the median values of elevation, latitude, longitude, and phenology between two periods (1900-1980 vs. 1981-2022) were tested. Records of in the period 1981-2022 showed median values of elevation and latitude higher than those recorded in the first period. Thus, in response to rising temperatures, the species became more frequent at higher elevation and in northern places. By contrast, does not seem to have changed its activity pattern in response to increased temperatures, but this might be an artifact due to the inclusion of likely overwintering individuals. The results obtained for indicate that even thermally euryoecious species can show changes in their elevational and latitudinal distribution, and that poleward shifts can be apparent even within a small latitudinal gradient.
关于气候变化对昆虫影响的文献数量日益增多。然而，迫切需要对关键领域中代表性不足的群体开展更多实证研究，这些领域包括气候变化影响可能不太明显的物种。本文阐述了在地中海盆地区域尺度上，对一种常见的森林拟步甲（皮勒和米特帕赫尔，1783年）进行研究的结果。利用来自拉齐奥（意大利中部）的大量记录，测试了两个时期（1900 - 1980年与1981 - 2022年）之间海拔、纬度、经度和物候中位数的变化。1981 - 2022年期间该拟步甲的记录显示，海拔和纬度的中位数高于第一个时期记录的值。因此，随着温度升高，该物种在更高海拔和更北部地区变得更为常见。相比之下，该拟步甲似乎并未因温度升高而改变其活动模式，但这可能是由于纳入了可能处于越冬状态的个体而产生的假象。该拟步甲的研究结果表明，即使是广温性物种也可能在海拔和纬度分布上出现变化，并且即使在较小的纬度梯度内，向极地的移动也可能很明显。
