How about huge numbers of eggs laid a few a day over the course of a season
or, in tropical species, continuously?  The older siblings would protect 
their nestmates from being trodden on by careless parents and maybe perform 
whatever other care was required.  I imagine the juveniles could best 
acquire their no doubt complex gut flora by eating older individuals' 
regurgitated food or even faeces.  They're beginning to sound like termites.
