Carnivorous plants actually make their 'death traps' stickier and more lethal while they are flowering and trying to attract pollinators.

The Takeaway
In an evolutionary paradox called the 'pollinator-prey conflict,' carnivorous plants risk eating the very insects they need to reproduce. This study discovered that instead of making traps safer to protect their helpers, sundews turn up their glue strength to be even more deadly during their reproductive season.
From the abstract
Premise: Carnivorous plants face a dilemma: acquiring nutrients from insect prey while simultaneously relying on insect pollinators for reproduction. Thus, carnivorous plants have evolved mechanisms to avoid/reduce pollinator-prey conflict. This study aims to understand how carnivorous plants deal with this conflict through: macroevolutionary adaptations (floral stalk length) or short-term physiological adaptations, such as modulating trap stickiness. Methods: I conducted a field experiment with
