[1][2][3] This species is known for its role as an agricultural pest, particularly in rice fields, where it feeds on developing grains by piercing them with its proboscis.

Oebalus insularis has a shield-shaped body typical of stink bugs and features a distinctive brown coloration with yellow markings on its scutellum.

[1] Oebalus insularis is primarily found in tropical and subtropical regions, including Florida, where it has recently established itself in rice-growing areas.

In Florida surveys conducted in 2008 and 2009, it was the second most abundant species, comprising 20% of all stink bugs collected and present in all sampled fields.

Adults and nymphs use their piercing-sucking mouthparts to suck the sap from the plants and developing seeds, producing 'pecky' rice.
