Final answer:
Female Photuris fireflies indeed sequester toxins by preying on male Photinus fireflies, utilizing mimicry to lure them in, which is true. The correct option is A.
Step-by-step explanation:
The statement Female Photuris fireflies sequester their toxins from male Photinus fireflies is true. Female Photuris fireflies are known for their deceptive practices where they mimic the flash patterns of female Photinus fireflies.
When a male Photinus responds to what he perceives as a potential mate, the Photuris female eats him and sequesters his toxins, which she then uses for her own defense.
This behavior provides a clear example of how one species' response to information can affect natural selection in another species, as male Photinus fireflies that are able to better discern real mates from predatory Photuris may have better chances of survival and reproduction.
