I’ve never seen them in WA, OR, ID, MT, CA, NV, or AZ. But I’ve seen them in the Midwest.
Do they exist in the West? If not…why?
Thanks!
I’m from the state of Washington and I never recall seeing fireflies here.
If breeding populations were introduced here from the Midwest, could they survive and eventually thrive here?

According to this, although members of the firefly family are found in the western US, ones that fly around flashing are not found much farther west than Kansas City.
Guess as to why?
No idea.
They’re pretty common in eastern Nebraska.
I see them regularly here in Texas- but that may not count as sufficiently “West” in your estimation.
Hippies. Fireflies hate hippies.
Obviously it is because FOX cancelled Drive before Mal could get far enough west…
Wait, what’s this thread about again?
There are planty of Fireflies in the Western USA. However, they don’t give off light. Yeah, I know, you think I am being a smartass. I am- but not here. 
I have seen the larval forms of the beetle Family Lampyridae right here in CA, and glowing quite nicely, thank you. Not common, but you can find them. However, the Western US species don’t produce light as adults.
From Wiki:
*Many fireflies do not produce light. Usually these species are diurnal, or day-flying, such as those in the genus Ellychnia. A few diurnal fireflies that primarily inhabit shadowy places, such as beneath tall plants or trees, are luminescent. One such genus is Lucidota. All fireflies glow as larvae. Bioluminescence serves a different function in lampyrid larvae than it does in adults. It appears to be a warning signal to predators, since many firefly larvae contain chemicals that are distasteful or toxic.

OK?
You can have mine, but you’ll have to round them up yourself. Bring a BIG jar.
I hate butterflies, too. Bugs. shudder
I’m lining up for Ms. Pumpkin’s fireflies. I’ve never seen them–I haven’t been very far east in either Canada or the USA. I’ve always wondered about them, and figured it was just a geographical distribution of species. They sound enchanting. I’m sure, like fireworks, they’d be “nice” on camera, but that’s not the same as seeing them in reality.
I’ll take your butterflies, too, although we are blessed with those here.
Maybe I’ll go to the ocean and look at the phosper… phosphorescence in the waves tonight. That’s all I’ve got for a ‘glow’ that I can think of!
They ‘enchant’ the crap out of dogs.
There’s one, I’m gonna eat it—WTF where’d it go 
I wouldn’t call them enchanting. Neat…interesting…fun to watch, but not really enchating.
If you’ve never seen one*, it’s not a nice warm glow, slowly flying around.
They only stay lit for a second or two (enough time to travel just a few feet) and it’s a bight flourescent green color.
However, if you do happen upon them someday, make sure you take the oppertunity to swat at a few of them. If you hit them hard enough, they light up as they whiz through the air or you can smush them on the sidewalk for a glow in the dark trail.
*'one is a bad term. That should be 'if you’ve never seen them. When they come out, they usually come out in full force and you see them all over the place.
I’ve often wondered if many people freak out the first time they see a firefly, if they had never heard of them before.
There are lots of fireflies in Malaysia, but they seem to behave a little differently than the ones in North America.
… 
It never occurred to me that y’all didn’t have fireflies. That actually makes me a little sad…and it makes me appreciate the little guys a little more.
Savannah, they ARE enchanting. I don’t care what Joey P says.
There is nothing like that moment when twlilight is waining and the lightning bugs rise up out of the meadow or lawn.
Yup, lightning bugs are one of many excellent reasons to go roaming in the gloaming round these parts.
That can’t be it, cause we totally got both.
I read once about fireflies that glowed on and off as a group. It was as if they had a timer on. Anyone know anything about them?
We Kansas Citians get all the cool toys.
