  Main sequence stars hosting extreme quantities of inner planetary system
debris are likely experiencing transient dust production events. The nature of
these events, if they can be unambiguously attributed to a single process, can
potentially inform us on the formation and/or early evolution of rocky
Earth-like planets. In this contribution I examine some of the dustiest main
sequence stars known and three processes that may be capable of reproducing
their observed properties. Through this activity I also make an estimate for
the likelihood of an A-type star to have an asteroid belt-like planetesimal
population.
