“…When studying beetles in the southwest of Primorsky Krai, all available methods of collecting were used: manual collection, collection with an exhauster, installation of soil traps, shaking off the crowns of trees and shrubs, catching by electric lamps, night collection with a flashlight, “trampling” of vegetation in wet and swampy biotopes, pouring water in near-water areas, sifting the litter with an entomological sieve, “mowing” the grass with an entomological net and catching with window traps ( Chapman and Kinghorn 1955 , Hardwick 1968 , Stewart and Lam 1968 , Gillies 1969 , Vanhercke et al 1981 , Kryzhanovskij 1983 , Schauff 1986 , Spence and Niemelä 1994 , Dunaev 1997 , Yahiro and Yano 1997 , Skvarla et al 2014 ).…”
