Tiny. While browsing my pictures, I came across quite a few that fit the theme, but narrowed it down to two.
The first is a picture of some aphids on the stem of an Dahlia plant. See them? They are the tiny yellow things. See the ants? They are "milking" the aphids for their honeydew secretions. It's true - I even checked here. This is something I observed last year and didn't believe Husband when he told me. I should have believed him, after all, he was right about Ant Lions and other odd facts I never knew.
The second picture is of a yellow crab spider hiding camouflaged on a sunflower.
