Abstract: The morphological structure of mature larvae of Attalus (Attalus) elongatulus
Lewis, 1895 as well as its bionomics and life cycle are described for the first
time. In the family Malachiidae, an univoltine life cycle is newly disclosed,
and the sclerites on the larval abdominal tergites are discovered for the first
time in this study. The microhabitat of A. elongatulus remains insufficiently
explored, although the adults were found on the plants of cliff-lined coasts
such as Pittosporaceae and Lauraceae. Two overwintering mature larvae were found
on the rocks on the seashore. It is suggested that this species locally inhabits
the warm microclimatic zones with a rich flora along cliff-lined coasts
dispersed within the temperate zone of Japan.
