    Studies of insect assemblages are increasingly needed to elucidate the pattern of insect diversity and the factors that affect them because many insects are declining due to environmental and land use change, and contribute to various ecosystem functions and services, such as herbivory, decomposition, pollination of fruits and crops, and pest control. In this paper, I explain (1) appropriate research design, (2) evaluation of sample effort and estimation of species number, diversity, and coverage, and (3) indicator species analysis, which are very useful for the studies of insect assemblages but have not been well described in Japanese so far. I illustrated analytical examples using our data on surveys of butterfly assemblages in clear-cuts and grasslands which were already published elsewhere. I also provided R code for these analyses. Some advantages and limitations of these analytical methods were discussed. All the data and R script used here are available from the electronic repository.
