the NE part is situated in a taiga zone, whereas the other part of terrain is in the European forest zone. The distance of Belarus to the steppe zone is about 330 kilometers. This geographical position and the extensive knowledge of its fauna can be used to monitor changes in the distribution of different species. An intensive study of open habitat ground beetles was carried out from 1975-2008 in Belarus, using pitfall traps, quadrate-sampling methods, hand collecting, netting and light traps. In total, more than 130 000 specimens of ground beetles belonging to 169 species were collected from 62 fields and 11 meadows of different types. 217 specimens of Calosoma investigator (Illiger 1798), 2 specimens of Calosoma denticolle (Gebler 1833), and one specimen of Harpalus subcylindricus (Dejean, 1829), Harpalus honestus (Duftschmid 1812) and Zabrus tenebrioides (Goeze 1777) were present in this material. All specimens were macropterous and exclusively caught at fields and waste grounds on sandy soil. Nowadays Belarus is the northernmost location for these species in Eastern Europe. Steppe species most probably migrated to SE Belarus from NE Ukraine, using Dnieper and its river valleys. The shift in the geographic distribution of steppe species during the last thirty years in Belarus have been attributed to a higher frequency of warmer and wetter summers in the last few decades.
东北部位于泰加林带，而地形的其他部分则处于欧洲森林带。白俄罗斯到草原带的距离约为330公里。这种地理位置及其丰富的动物区系知识可用于监测不同物种分布的变化。1975年至2008年期间，白俄罗斯对白蚁科昆虫进行了深入研究，采用陷阱诱捕、样方抽样、手工采集、网捕和灯光诱捕等方法。总共从62块田地和11种不同类型的草地中收集了超过130000只属于169个物种的步甲科昆虫标本。该材料中有217只调查步甲（Illiger，1798年）、2只齿缘步甲（Gebler，1833年）以及1只亚圆柱形婪步甲（Dejean，1829年）、正直婪步甲（Duftschmid，1812年）和暗黑步甲（Goeze，1777年）。所有标本均为长翅型，且均在沙质土壤的田地和荒地捕获。如今，白俄罗斯是这些物种在东欧最北的分布地点。草原物种很可能从乌克兰东北部经第聂伯河及其河谷迁移至白俄罗斯东南部。过去三十年间白俄罗斯草原物种地理分布的变化归因于近几十年来夏季温暖湿润频率的增加。
