Abstract Until today, most information about the natural history and ecology of soldier beetles came from temperate zones, mainly from Holarctic areas, while tropical regions have been poorly studied. The aim of this contribution is to compile and synthesize information concerning the natural history and ecology of Cantharidae (Coleoptera) from the Mexican tropical dry forest (TDF), to serve as a starting point for more in-depth study of the group in one of the Mexico's most endangered ecosystems. All compiled data on the family have been organized into the following topics: distributional patterns and habitat preferences, feeding behavior and host plants, and daily and seasonal activity cycles. For the first time, it was provided a list of host plants for TDF Cantharidae genera and species, and it was also observed a high ecological diversity in the phenology and behavior of TDF Cantharidae assemblages. Further research concerning cantharids and other TDF insects needs to have a more comprehensive and integrated approach toward understanding the patterns of distribution and diversity, and elucidating the role that cantharids play in ecosystems, especially in TDF, which is one of the most endangered ecosystem in the world.
