Trophic relations of lichen-feeding darkling beetles of the tribe Helopini in Turkey, the Caucasus, and Anti-Atlas are considered. This group is the most diverse in relict Anatolian forests of Cedrus libani, Abies cilicica, Pinus nigra, Juniperus spp., and Quercus cerris, where multitaxon lichenophagous assemblages exist. Three life strategies for attenuation of interspecific competition are distinguished: (1) differentiation of the consumed lichens, (2) separation of the life forms based on the types of the lichens consumed, and (3) segregation of circadian activity in adults. We assume that adaptation of the Helopini larvae to the soil life promoted their wide distribution in dif- ferent landscapes by elimination of the limiting factor for completing their life cycles, namely the need for ligneous substrate of old rotting trees. The possibility of using lichen-feeding beetles of the tribe Helopini in ecosystem and lichen indication is considered.
