The term morbilliform refers to a rash that looks like measles. The rash consists of macular lesions that are red and usually 2–10 mm in diameter but may be confluent in places.
Drug hypersensitivity reaction. Eczematous, targetoid rash on the trunk occurring 1 week after the administration of a systemic cephalosporin.
Morbilliform drug eruption usually first appears on the trunk and then spreads to the limbs and neck. The distribution is bilateral and symmetrical. The primary lesion is a pink-to-red flat macule or papule. Annular, targetoid, urticaria-like or polymorphous morphology may occur.
Initially, there are erythematous blanching macules and papules, which may coalesce to form larger macules and plaques. The term “morbilliform” connotes a measles-like: the rash of measles is classically described as having macules that are 3 to 4 mm in size that coalesce. MDE is usually itchy.

The genus Euschistus includes several species of stink bugs that are similar in appearance and biology to H. halys. They are all brownish in color, and have a wide host range that includes field crops, vegetables, fruits, and nuts. Some of the more common include:
The spined soldier bug (Podisus maculiventris) is a common predatory stink bug that occurs throughout North America. Sides of pronotum pointed. The first segment of the proboscis (nose-like extension from the bug’s head) is shorter and thicker on the spined soldier bug versus BMSB. Antennae are often reddish.
Stink bugs in the genus Brochymena are commonly referred to as rough stink bugs, and are known to feed on both plants and other insects. Two of the more common species are B. quadripustulata and affinis. These species are relatively uniform brownish gray in color, and have a roughened, somewhat flattened appearance. The rough stink bug differs from the BMSB by the presence of a “tooth” on each side of the face and a row of spines on the shoulder area.

Taking a look at its shape, stink bugs have a shape similar to the earth’s body, almost what you would call oval However, this is not as astounding as its triangular shaped body, what an entomologist would refer to as a ‘triangular scutellum’. The color of a stink bug depends on its genus and species.
Jul 15, 2013 · But now there’s evidence that these pesky stinkers might actually be good for something. According to an article published this year in the Annals of the Entomological Society of America, Mike Raupp and colleagues conclude that they may actually help feed some wasps and ants by wounding plants, which then leak sap that the wasps and ants can feed on.
