What is this red bug? Is it dangerous?
The first photo is a fungus that often grows in mulch, particularly in wet weather. It's called birds nest fungus. Look here : https://extension.psu.edu/what-is-growing-in-my-landscape-mulch-mushrooms-slime-molds-and-fungus
The second and third photos are pretty fuzzy, but we think they are boxelder bugs. Look at the different life stages on our webpage: https://extension.umd.edu/hgic/boxelder-bugs-trees-and-shrubs
