I was driving the new Mustang to work on Tuesday when something
fluttered past in front of my face. It was a big moth, about an inch
and a half long. Must have hopped a ride when I first got in. I go to
work very early, and that's when little beasties like that are out and
about.

It looked a little like this:

No biggie. Better than a pissed off wasp or a carpenter bee (both of
which I have shared vehicles with). I opened the passenger window. He
fluttered around the back window for a while. When I got to work, I
looked around the interior, but I figured he made his way out.

At 2:30 am this morning I wake up to the sound of the Mustang's car
alarm going off. It took me a few moments to gather my wits (such as
they are), find the remote in the dark, and silence/rearm it. I'm sure
my neighbors love me. Good Lord is a beeping car horn subjectively LOUD
at that time of night.

No one seemed to be around. Even the car theives are home in bed at
that hour. When I went to work four hours later, there was no obvious
sign of anyone mussing with the car like hand prints in the dew or
anything. I couldn't figure it out because this isn't some $100 Best
Buy discount alarm system that goes off when someone sneezes a 1/4 mile
away.

I get home today, and just as I'm pulling into my driveway, the moth
flutters by again and lands on my shirt. I grab him with my hand and
make sure he comes out the car with me and release him outside.

The way I figure it, the Mustang has two ultrasonic motion sensors on
the small overhead console up front. I'd wager a week's salary the moth
either fluttered right in front of it or even landed on it, and set of
the alarm.

So that's how a little moth woke me up at 2:30 am and annoyed people
for a one block radius around my house.
