Data from: Release from prey preservation behavior via prey switch allowed diversification of cuticular hydrocarbon profiles in digger wasps

Mareike Wurdack, Carlo Polidori, Alexander Keller, Heike Feldhaar & Thomas Schmitt
The cuticle of insects is covered by a layer of hydrocarbons (CHCs), whose original function is the protection from desiccation and pathogens. However, in most insects CHC profiles are species-specific. While this variability among species was largely linked to communication and recognition functions, additional selective forces may shape insect CHC profiles. Here we show that in Philanthinae digger wasps (Crabronidae) the CHC profile co-evolved with a peculiar brood-care strategy. In particular, we found that the...
