Sweet Potato Bug

Physomerus grossipes

Description:

Physomerus grossipes Fabricius, 1794. Wikipedia describes it as follows: "Brown in color with black legs, individuals grow to be about 2 cm (0.79 in) long. Like other Coreidae, P. grossipes is oval-shaped with segmented antennae, a numerously veined forewing membrane, a metathoracic stink gland, and enlarged hind tibia."

Habitat:

Spotted in our garden, a fairly large infestation feeding on Sweet Potato Plants (Ipomoea spp.)

Notes:

Wikipedia also points out that the females of this species guard their eggs and young nymphs to defend them against predation. I have taken some pictures of this and will upload a spotting dedicated to this significant maternal behaviour as soon as I have a spare moment.
