I keep seeing these little beetle looking bugs on my windowsill. They are 1-2mm and are kindof round. Under their shells they have wings and they fly. They are orange to brown in color. They have black-ish zigzag markings on their shells. Their underside is a whitish gray color. Most of them are in the track that the window slides on to open, but some are on the windowsill. Most of them are dead, but some are alive. They crawl around slowly but they can fly pretty fast. They are like ladybugs in shape, but are much smaller. What are these? Are they harmful in any way to my plants by the window? My sundew has no dew so it can't catch them and I'm worried that they could be harmful to my plants.
