it is B. ( wonderful poetry )
It is not A : the flash of a firefly does not prevent some other fly to mate with the firefly, ther are other barriers the fly has to take.
C) the firefly does not confuse predators, no they atract predators of their predators with their light, but this is not the case with the song of the bird.
D) migrating ? firefly dont migrate.
B() ? neither

It's A.
Here's why:
D) Fireflies don't migrate.
C) Signalling that you're around, like a firefly, is not a good way to confuse a predator. Really, it's much better to do things like shut up.
B) Silk Moths and Fireflies are not territorial.
That only leaves A.
And keep in mind that only male fireflies actually fly - females are flightless. But both blink on and off during mating season.
And if all of that is true for fireflies, it must be true for the others.
Now, some songs for sparrows are to mark territory, as sparrows have some territorial behavior. But your textbook will tell you that the silkmoths are one of the best-studied examples of pheremone production/reception in the natural world, which is another clue pointing you to A.

certainly not B like people are saying
I would pick A....i know the chemicals by the moth are phermones or something that attract mates, so are the songs and lights..so A I am positive

I would definatly mark out C, and I belive that it's B, just cause it's a big thing.

Zits comic strip covered this, and How Stuff Works does also. It is a mating ritual.
