Corotoca (Coleoptera: Staphylinidae) beetles are known for their close integration in the nests of the termite Constrictotermes cyphergaster (Termitidae: Nasutitermitinae). Although this relationship is regarded as ancient, many details are still obscure, such as their reproduction and the processes that lead to the dispersal of new beetles. We observed the use of termite foraging trails by Staphylinidae females to deposit and disperse their larvae. We recorded the deposition of larvae of C. melantho, C. fontesi, and C. sp. n. on the dorsal surfaces of termite host workers. The workers continue to follow the foraging trail until the newborn larvae freed themselves and fell into the leaf litter, subsequently burrowing into the ground. Information regarding the life stages of those Staphylinidae larvae outside the termite nest is important to understanding their full lifecycle as those taxa have strong relationships with the nest environment but also require dispersal strategies.

This note reports the occurrence of carcass feeding by Nasutitermes callimorphus, a endemic termite from brazilian evergreen forests. Based on this observation and previous reports, it is plausible to think that drought may play a important role in the occurrence of necrophagy in termites.

The variation in altitude drives the richness and density of species in tropical ecosystems. The diversity and richness of termites are influenced by the variations in temperature, humidity, and soil properties according to altitude elevation. This is well known for rainy forests and little information is found for semiarid areas of Brazil. In this study, we aimed to identify species richness and encounters density of termites in a hill inserted in the Caatinga Brazilian forest. We found variation in the composition of species as a function of altitude (in a comparison of top and foot of the hill) and in periods of the wet and dry, with an increase in the season wet. The increase the diversity in this period and altitude elevations can be explained by the increases in humidity after rainfalls and maintenance of temperature enabled by the conditions in the hill’s top. Our findings provide valuable information regarding termite diversity in semiarid areas as a function of elevation and contribute to other studies that are expanding our understanding of how elevation can affect these organisms.
