Where in the US are there fireflies? (area, humidity)

[xboxmas]

I have never seen them on the West Coast, and saw some when we went to Wisconsin one summer. I thought they were cool looking at night. I haven't noticed them in any other states I have been to(Washington, Oregon, California, Utah, Hawaii, Nevada, Florida, Idaho, etc) and was just wondering where they distribute and what states I can expect to see them in if I were to travel across the country some day.

NJ and PA have them.

We have them on this part of the Gulf. Texas too.

I have seen them in Cleveland and grew up catching them in Chicago.

We have them in the Baltimore area

Virginia, NC, and SC, too.

We definitely have them here in Illinois. I've seen them in Wisconsin and Iowa too.

Someone once told that generally, you don't see fireflies (or as we say in my family, "lightning bugs") west of Kansas. I found that to be true. I've seen them in TN, MO, SC, GA and even in Florida (panhandle). They need humidity, lots of moisture/water and woods.

I think mostly in the Midwest....from my travels Ohio, Indiana, Illinois and Michigan seem especially full of them.
