The same windfall apple that the Wasp was on, now hosts a fly. If you wish to take a closer look, below the eyes, and reaching down to the apple, is its proboscis, which it uses to eat with.
If you look at the ends of its legs, on the bottom of its feet, you can see white bits. These are its Pulvilli, little adhesive pads, these are what let them climb up smooth vertical surfaces like glass windows.
