If it looks like a stinkbug, don't be a dumbass and squish it.
It will not go well for you.

Sorry the duke but you are wrong, it's not fake news........

It is easy to mix these two up because they share the same "shield" shape and brownish color, but they play opposite roles in your garden. The Brown Marmorated Stink Bug (BMSB) is an invasive pest that destroys fruit and vegetables, while the Spined Soldier Bug is a native "good guy" that eats the pests.
The most reliable way to tell them apart is to look at their shoulders and their antennae.

Detailed Differences​

1. The "Shoulder" Test​

As the name suggests, the Spined Soldier Bug has distinct, thorn-like points sticking out from its shoulders (the pronotum). If the shoulders look like they could poke you, it's likely a soldier bug. The BMSB has much more rounded, "sloping" shoulders.

2. The Antennae "Check"​

If you can see the antennae clearly, look for white segments.

• BMSB: Always has two distinct white bands on its dark antennae.
• Soldier Bug: Its antennae are generally a uniform reddish-brown or tan.

3. The "Beak" (Proboscis)​

If you are brave enough to look at its underside (or see it through a glass jar):

• The Predator: The Spined Soldier Bug has a beak that is roughly twice as thick as its antennae. It needs this heavy-duty hardware to hunt caterpillars and beetle larvae.
• The Pest: The BMSB has a very thin, straw-like beak used only for drinking plant juice.

4. Behavior​

• BMSB: Usually found huddled together on the sunny side of buildings in the fall, or feeding on tomatoes, peppers, and fruit.
• Spined Soldier Bug: Usually found alone, actively searching for a meal. You might even catch it in the act of eating a caterpillar or even a BMSB nymph!
