Wildlife Spotting

I put all the photos in one spotting because I wanted people to give guess about the similarity and difference between the three insects. I would like to keep them together until I can get more information about this genus. I thank the comments of Leuba, Armadeus and scott.

Hello, nacho, I am intrigued by these bugs. Answering the question of Leuba, everyone was on the same plant. There are a lot of females sitting on the eggs. Some eggs are whitish, others are pink and others are orange. So I think they are three different species belonging to the same genus. Yes, it's a couple of pictures of each insect. The plant is a type of fabaceae, beans. stephanielrickman you is always very kind. Thank you.
