Bronze Shieldbug - Troilus luridus

Length 10-12 mm. A large predatory shieldbug which has an orange band on the penultimate antennal segment. The legs are brown and the scutellum lacks an orange tip, further distinguishing this species from the Forest Bug. In addition, the frontal projections of the pronotum are more rounded.There are two colour forms of the final instar nymph - red and cream.

This woodland species is associated with both deciduous and coniferous trees.

Adult: All year.

There is one generation per year; the nymphs feed on plants as well as the larvae of other insects, particularly caterpillars. Early instars may appear similar to those of the Blue Bug. New adults may be found from July onwards.

Occurs widely across Britain and Ireland but is not common.

Occasional in Leicestershire and Rutland.
