Everything is covered in pollen in Texas in the Spring. A thick nose-watering blanket of yellow dust also covered my front bench, which used to be black. Something struggled through that pollen and left strange marks in the film.

My current hypothesis is that an insect from the Lepidoptera family landed on the right side of the bench, crawled, wings flapping through the pollen, and something mammalian with non-retractable claws caught and munched it on the left side of the bench. Reducing it to the simplest and most likely candidates based on population density in our area perhaps it was a large moth (polyphemus maybe?) eaten by an opossum.
