Larvae of the tineid subfamily Harmacloninae are thought to be wood borers without firm evidence. Moths of this subfamily have also well-developed tympanic organs on the second abdominal segment. Among microlepidopterans, this type of organs occur only in Harmacloninae and Pyraloidea. In 2022, we obtained larvae of Micrerethista denticulata Davis, 1998 belonging to Harmacloninae from tunnels in the dead trees of Quercus serrata in Hashimoto, Wakayama Prefecture, Japan. The life history of M. denticlata, including the morphology of the immature stages is described on the basis of field observations and rearing. This represents the first definitive evidence of wood-boring habits in larval stage for the subfamily. The evolution of the larval and pupal morphology associated with wood-boring habits is discussed and the role of the tympanic organs in Harmacloninae is speculated.
