ELI5: Why is it that bright colours in plants are an invitation, but bright colours in insects and animals can be a warning?
gpt
Bright colors in plants are to attract bees and insects for pollination. Bright colors in animals/insects make them easily spotted by predators, so these bright colored animals/insects die out - except for the very venomous/dangerous ones,  i.e poison dart frog or those with low selective pressures, i.e birds where camouflage doesn't matter as much.
