Image of Riptortus serripes (Fabricius 1775)

Description:

A gathering of these bugs on the long grass in a weedy area, mid-morning. Nymphs and adults were present. The group was right next to a busy colony of green tree ants (Oecophylla smaragdina) but they weren't nearly as active as, and didn't seem to be in direct contact with the ants.
