Troilus luridus, also known as the bronze shieldbug, is a species of shield bug found in Europe.

Shieldbugs are generally phytophagous (i.e., feeding on plant sap) and some, including Troilus luridus, are also carnivorous and will eat the larvae of beetles, lepidoptera and sawflies.

[2] Troilus luridus is a large predatory bronze-brown shieldbug in the family Pentatomidae.

It measures about 10 to 12 mm in length and has a distinctive, orange band on the penultimate antennal segment.

[1][5] Although never seen in great numbers, it is probably very common as it inhabits trees and those seen in the lower branches are a small fraction of the population.
