Description
“A flat brown soldier bug (Cermatulus nasalis) has been noted to have an appetite for monarch larvae. This 10mm long bug looks like a small version of the common green vegetable bug, except that it is dark brown with a yellow crescent mark on its back, between the wings. It feeds by spearing the larva on its long hollow beak and sucking out its contents. The soldier bug is found in Australia and New Zealand.” (Gibbs, 1994)
