Figure 6. Late instar nymph from the genus Brochymena. Nymphs from this genus may be mistaken for the brown marmorated stink bug, Halyomorpha halys (Stål), nymphs due to the presence of spines on the humeral margins. They can be differentiated from the brown marmorated stink bug nymphs by the absence of clearly defined white stripes on the antennae.
