I have noted this particular bug in my yard many times. As of late I have noted them on my Habanero plants. Something is eating the leaves of my plants and at the moment this is the only insect I can find on them. Before I try eradicating them I would like to make sure they are not beneficial insects and eating some little critters I can not see. I've watched them for a bit and to be honest all I ever see them do is "stand around" :-) They are a dull black in color with red eyes, 2 red markings on the thorax(?), and on their lower back. Does anyone have an idea as to what this insect is and if it eats plants? Thanks!
