"Nothing in nature pretends to love, but then tries to eat you."

Actually there are.
Anglerfish: The anglerfish uses a bioluminescent lure to attract prey in the dark ocean depths. While this isn’t an emotional lure, it can be seen as a deceptive behavior to draw victims closer.

Spiders (like the Bolas spider): These spiders emit chemical signals that mimic the pheromones of certain moth species. Male moths are lured in, thinking they’ve found a mate, only to be captured and eaten.

Orchid mantis: This insect resembles a flower to attract pollinators. Unsuspecting insects approach, thinking they’re landing on a flower, and the mantis grabs and devours them.

Cuckoo birds (brood parasites): Cuckoos lay their eggs in the nests of other birds. While this isn’t direct predation, the parasitic chicks often push the host's eggs or chicks out of the nest, monopolizing the care of the host bird.

Femme fatale fireflies: Certain species of fireflies mimic the mating signals of other firefly species. Males are lured in, thinking they’ve found a mate, only to be eaten by the female.
