Macrolophus pygmaeus is a predatory bug used in the biological controlling of Greenhouse whitefly (Trialeurodes vaporariorum) and Tobacco whitefly (Bemisia tabaci). This predatory bug is also a predator of spider mites and, less extends, aphids and leaf miners. Adults are 6 mm. in size, green coloured, delicately build with long legs and antennae. Observing the eggs cannot be done due to the placement of these eggs inside the leaves. Nymphs are yellow-green coloured and mostly seen on the bottom size of the leaves.
