I thought this was a Spined Soldier Bug. The red patch on its back is not in any information I have found.
The angle of view of your photo makes it difficult to ascertain for certain that this is a Spined Soldier Bug, Podisus maculiventris, but we believe that you are probably correct because of the spines on the pronotum at the widest point of the body. A photo posted to BugGuide shows some reddish markings on the individual as well as reddish legs. Perhaps there are some latent genes that may eventually result in a population with red markings for this beneficial Predatory Stink Bug.
