High in the canopy of an old black walnut, a black squirrel is eating a pendulous catkin -- the male flowers of the tree (tree: "Juglans nigra", squirrel: melanistic eastern grey, "Sciurus carolinensis").
This is one of my favourite insects in our biodiversity garden. First, it is a bumble bee mimic. Second, it is a predatory fly, and it's eating a Japanese beetle, a notorious introduced plant pest that feeds on an unusually wide variety of plants -- and always your favourite one! (robber fly: "Laphria" sp., family Asilidae; beetle: "Popillia japonica", family Scarabaeidae").
