The plant ate it? Not as unlikely as some might think ...

Carnivorous plants - plants that tempt, kill, and eat insects - like the pitcher plant which is the emblem of Canada's province of Newfoundland, are found most often in bogs.

Bogs (wetlands) are low in nitrogen. Insects, however, are high in nitrogen. Therefore some bog plants -which need nitrogen to live - rather than going out of business, have taken to eating insects.

Some scientists, such as Granville Sewell, treat the plants' elaborate traps the plants construct as an instance of irreducible complexity.

These elaborate plant traps did not arise by Darwinian evolution, as taught in school, because it is implausible that - at every stage of their construction - they helped the plant survive and leave seeds. They could not likely have helped the plant in any way before they landed an insect.
Here's an article on "lily con carne," so to speak.

Want to keep a carnivorous plant as a pet? They're fun but learn their needs or lose your investment. Carnivorous plants are a highly specialized life form.
