The various critters in my yard slow down my mowing since I have to wait for all the little bunnies to get out of the way of the mower. And the toads, frogs and the little spotted fawn. And I even had to stop for a butterfly, Red-spotted Purple, when I saw it trapped in the window screen. It is mainly a black butterfly with iridescent blue with red spots and it is often found taking nutrients from gravel roads, roadsides, or scat.
