We have them everywhere around here. Brown and green. They came into the country through a shipment of something into Pennsylvania and set up shop. There's houses that have dead ones piled up knee high in the attics. They feed on plants in the summer and overwinter in houses. They love soy and the farmers here will rotate soy into their crops every couple of years for fertilizer and it just breeds stink bugs. Super annoying in the house. I've never seen them on cannabis plants though
