Whenever I planted french beans or 4 angle beans, there are these black beetle size about ladybug and acts and walks like ladybug, maybe a little faster. It likes to stay together like a chain on the vine. It doesn't seem to be active during day time nor at night. My french beans have got lots of blossom drop, I wonder it has anything to do with these beetles. When I tried to catch it, it just drop to the ground and when I squish it, it smells like stinkbug. What are they?pest or........My earlier french beans got very little fruits and die for no reason when on the ground. I now planted at my first floor balcony and it has got quite abundance of fruits except earlier there are lots of blossom dropped. Still now but at least I now see some fruits. These guys fly to my balcony for quite a while already. I wonder what they are doing there! Do I get rid of it? Thanks, Engy
