de-Barking in Costa Rica

With a little over 30 species, Homalolinus is a predominantly Central American Xantholinini that inhabits subcorticular habitats (lives under bark of dead trees). I have found that fermenting, gooey subcortex is best, and this statement goes for other staphylinoids as well. Several genera/species of Hydrophilidae and aleocharine staphylinids such as Diestota are quite abundant under the bark of of trees undergoing some fermentation.
