The harvest mite is a tiny orange or red mite, so small you can hardly see it. Its babies wait on blades of grass and grab on to animals and people walking by. Their bites can make your skin very itchy.

Fun fact: this one is not an insect. It is an arachnid with eight legs, a cousin of the spiders.
