Acanthocoris Coreid Bug

Brown coreid bugs, about 13-15mm in length (excluding antennae), spotted on an Ipomoea sp. plant, in the weedy part of the backyard.

The young of this species can be seen here - http://www.projectnoah.org/spottings/16974810.

Acanthocoris scabrator (Fabricius, 1803), of family Coreidae, subfamily Coreinae Leach, 1815, tribe Acanthocorini Amyot & Serville, 1843, genus Acanthocoris Amyot & Serville, 1843. Adult Acanthocoris scabrator (12-15 mm) occur in groups and are mostly found feeding on non-crop host plants such as Ipomea and nightshades. They feed only occasionally on crops such as pepper and are not considered pests. Although a related species, Acanthocoris scaber (Linnaeus) 1763, has been reported as a major pest in Southeast Asia.

Although there's slight difference in the wing coloration, these adult coreid bugs look a lot like my previous spotting - http://www.projectnoah.org/spottings/17209951.
