FIGURE 2.

Phylogenetic tree of termites, simplified from Bourguignon et al. (2015), showing the widely shared ability to build shelter tubes in termites. The genera retaining the ability to build shelter tubes without using them in natural conditions are underlined. Some genera were lumped together into higher‐ranked monophyletic lineages to account for the lack of research. The shelter tube building ability of Stolotermitidae is based on observations on Stolotermes, and that of Hodotermitidae is based on observations on Anacanthotermes. Species of Kalotermitidae were lumped together as they all lack the ability for shelter tube construction. We found no information about shelter tube construction in Serritermitidae + Termitogeton
