Corrected entry: You can see as PT Flea is walking away from the fly paper he has just torn himself off that the paper only just catches him on its edge as it falls, but when the shot goes back to where PT is floating in the water droplets, the burn mark around him on the floor is considerably larger than the area the fly paper actually fell on.
Corrected entry: In the opening scene, first shot, we see a bird fly left to right across a beautiful sky. A leaf falls into picture, causing ripples on water, a tilt-up revealing that we've been looking at a reflection on that water. The reflection of the bird was right-side up, but, as it is a reflection, the bird should have been seen as upside down.
Corrected entry: At the end of the film, where everybody's thanking the circus bugs, Heimlich the caterpillar's voice is heard saying, "Oh,thank you!" But later, we find out that Heimlich's been in a cocoon. He couldn't have been in the crowd and just left to make the cocoon, because it's impossible for a caterpillar to form into a butterfly that fast.
Corrected entry: The caravan (trailer) where the bug flies into the zapper at the "city", looks a lot like the one in Monsters Inc, where Mike and Sully throw Randall into.
Corrected entry: The first time we visit the circus, watch the one-spider band. He is only playing one trombone-like instrument, but the music he produces sounds like a brass choir. I didn't know that playing one straw could make that nice of a sound.
Corrected entry: This is actually a mistake for the Pixar short flik Jerri's Game, but as this is included in the A Bug's Life video, this is a good place to list it. Jerri (with glasses) knocks off the box of chess pieces after faking a heart attack, but when the camera pulls back at the end of the flik, you can see there is no chess box on the ground.
Corrected entry: With the grasshoppers rapidly approaching Ant Island, Flik is seen getting caught on a plant with his seed gathering contraption while trying to get to the antill quickly. He flips over sideways and all the seeds fall out and scatter. A few seconds later, as he runs to the Offering Rock, and the receptacle is once again full seeds. He couldnt have gathered up those stray seeds, taken off the contraption and refilled the holder and reattached the "machine" so quickly.
Corrected entry: With all the other bugs and scenery so realistically colored, why are the ants lavender blue?
Corrected entry: When the bird chases the bugs into the rosebush-type plant, it hovers outside, unable to get in. This bird is not a hummingbird, therefore it would be unable to hover.
