@nev it can happen that for example depending on the #mobility of the #beetle species and its #strategy to perform its #selfcleaning #behaviors that #phoretic and #parasitic #mites can be limited to small numbers only on an even relatively large #beetle. Most Scarabaeidae develop in #soilhabitats. But when it is #decayingwood or #compost, then this improves the probability that it has associations with phoretic mites. In beetles, #phoreticmites can sometimes be hidden under the elytrae.
