What is causing this damage to my rhubarb leaves? (picture attached)

Dakota County Minnesota

Expert Response

That looks like insect damage possibly four lined plant bug. As it is so late in the season for rhubarb I wouldn't worry about it. You could try watching for insects though and then use insecticidal soap if you find some.  https://extension.umn.edu/yard-and-garden-insects/four-lined-plant-bugs
