Because the flowers attract food in the form of insects. I must be missing something here.
Pitcher plants and flytraps use sugary secretions to attract prey not flowers.
Why would they want to attract flowers?
Because they’re pretty, duh
Both use flowers with long stems to keep the pollinators out of harm’s way. I grow both, seen it IRL.
Flowering plants use life to spread genetics. No reason to be carnivorous if there’s no reason for animals to crawl all over you
While all of these answers are mostly true, you have to go back in time. Darwin called it the abomniable mystery. Flowering plants and insects co-evolved rapidly roughly 150 MYA. So prior to flowering plants, there were few plants and insects and they were mostly generalists. The rapid expansion and explosion of insect diversity is deeply entangled with the explosion of diversity in angiosperms.
Is it vegan if you eat carnivorous plants?
Vegan enough for package labelling, not vegan enough for the psychic powers
Where are my plants that impregnate human females through their vines used as tentacles, as promised by hentai?
We just haven’t found the carnivorous trees yet. Those poor, poor squirrels…
Because they live in environments lacking in the nutrients that can be gained from invertebrates (e.g. in highly acidic soil). This allows them to compete better against other plants. I guess non-flowering plants don’t need the same nutrients so can go without. Only a beginnner+ at ecological botany so someone here can surely explain better knowing lemmy!
Ultimately it’s more about trapping and consuming live animals, I don’t really care if they actually chew.
