成虫は３月下旬～５月上旬にサクラなどの花でも稀に採集されるが、主にリョウメンシダの葉上で見られる。おそらくトビムシなどの小動物を捕食しているものと思われるが詳細は不明。本種はこれまで神奈川県の低地のみから得られているが、暖温帯の低地に広く分布していると思われる。

This species is observed mainly on the leaves of a fern species, Arachniodes standishii, from late March to early May, and is also rarely collected from the flowers of other plants such as cherry blossoms. It probably preys on small arthropods such as Collembola but its biology is uncertain until now. It has been recorded only from the plains of Kanagawa Prefecture in Honshu so far, but probably it is widespread in lowlands of the warm temperate region of Japan.
