  1. The %FO column shows the percentage contribution of a family to its order. The Location (Time) column shows the location and time a prey item was found in this study. Families that are marked with ^ consist members of economically important pests and vectors of insect-borne diseases. Genus and/or species with + are not recorded in Hong Kong before according to Lau (2019). The habitats of different insect families followed Hill et al. (1982), which SL = Soil and Litter, G = Grassland, F = Forest, FW = Freshwater, U = Urban, A = Agriculture and M = Mangrove. 1 Family Proctophyllodidae is an ectoparasitic family of feather mites and thus, this group was not treated as a prey item
