Species diversity of leafmining microlepidoptera was investigated in "Mt. Mikusa Zephyrus Coppice", Osaka, Japan, from April to November 2007 and from April to October 2008. As a result, a total of 34 species (10 families) were collected. On Mt. Mikusa, we found that various leafmining microlepidoptera were present, mainly utilizing deciduous broad-leaved fagaceous trees as hosts. In addition, it was thought that the species composition of leafmining microlepidoptera was affected, apart from vegetation, by forest management such as logging or weed clearing. We conducted a similar survey of leafmining microlepidoptera in the campus of Osaka Prefecture University located in the urban area of Sakai city, Osaka from April to October in 2008. On the University campus, 11 species (four families) of leafmining microlepidoptera were collected. On the University campus, the species were composed mainly of botanical or agricultural pests. Only three species, two nepticulids and a gracillariid, all feeding on trees of the genus Quercus, were common to both localities. Since the species composition is characteristic in each locality and affected by various types of forest management, it is suggested that leafmining microlepidoptera could serve as an environmental indicator.
