The X-Files, Season 9

Dr. Bronzino:
So many flowers... so little time.

Scully:
Excuse me?

Dr. Bronzino:
Pheromones, Dr. Scully. Heavy in the air. Nature's natural attractants. Driving the insect world to go forth and pollinate.

Scully:
I'm aware of how pheromones work. But according to this device there isn't a single pheromone to be found out here.

Dr. Bronzino:
Well, that can't be right. The bio-sensor we use is an actual fly antennae over which the pheromones pass. But I modified the EAG to measure in picograms which makes it sensitive to traces a mile in any direction.

Scully:
But I'm still not sure why you think that pheromones might cause an otherwise harmless fly to attack a human so violently, Doctor..

Dr. Bronzino:
Rocky.

Scully:
Rocky.

Dr. Bronzino:
Bugs are small-minded creatures, and therefore very predictable. They don't have moods, per se. They react to circumstance and stimuli, as they have been doing it for millennia.

Scully:
So what do you suppose they're reacting to out here?

Dr. Bronzino:
It may be the bugs are being somehow driven crazy with desire. You know, they say we humans respond to pheromones, too.

Scully:
Yeah, I tend to agree with that, yeah.

Dr. Bronzino:
'Women's dormitory syndrome' - It's believed that pheromones are the reason that women who live together share the same menstrual cycle.

Scully:
Fascinating.

Dr. Bronzino:
You know, when a male and female calliphorid fly mate they stay joined for up to one and a half hours. One and a half, doctor.

Scully:
You know, Rocky... I'm a mother.

Dr. Bronzino:
..Mothers are women, too.
