Description of Solenopsis geminata

Economic importance: Generalist predator
Hosts: Leafhoppers, planthoppers, bugs, and moths.
Description
1. Solenopsis is reddish to brown and has 10-segmented antennae with 2-segmented clubs. Its eyes are relatively larger than those of other species of ants.
Biology and ecology
1. Red ants make nests below the soil surface in upland fields and in bunds or levees in wetland rice fields. The nests they make are for workers and soldiers.
2. They colonize newly established fields and prey on different kinds of insects and small animals, including adult black bugs.

Description of Euborellia stali

Economic importance: Generalist predator
Hosts: Leaffolder and stem borer larvae.
Description
1. Euborellia stali is a shiny black earwig with sclerotized tegmina. It has white bands between the abdominal segments. Two antennal segments located near the tip are white.
2. Earwigs have a hind pair of forceps-like cerci. These are used more for defense than for capturing prey.
Biology and ecology
1. Earwigs are common in dryland habitats. They rest in the soil at the base of rice hills and are nocturnal.
