Taxonomic History

First described by Rossi in 1790. The Japanese records represent either the eastern limit of native distribution or a recent introduction.

Habitat Specificity

Unlike the related Berytidae (stilt bugs), which are primarily terrestrial vegetation-dwelling insects, Patapius spinosus is restricted to coastal marine environments.
