View Full Version : Anyone from northeastern US-Fireflies

Can anyone tell me what month fireflies first make an appearance in the northeastern US (western NY)?

It depends a bit on the weather but in N.H. it was / is June. Fairly early June, too, before school got out. By mid July our pasture would be thick with their glowing blinks.

I recall arriving in Lancaster PA in May, and the fireflies were already out - but this was in '93. Weather will have a bearing.

In CT, I always see them in June and July.

When it's warm. May, June. Soon as it's warm out. I think after there's much threat of frost (beyond the occasional freak cold snap.)

At least that's what it's like in Michigan. Usually before school's out (we're out end of May) when I get home after nigh class, there'll be a few winking fire flies trying to get laid.

Just in case anyone else has an older brother with an odd sense of humor, there are no fireflies with red or blue "lights"

Not true! If you drive really fast, you can get glimpses of them in your rearview mirror.

I think July or so in SW Connecticut. Maybe June. I'll come back to you in several months to confirm. ;)

I'm from Western NY. Late June. There are always a ton around by the Fourth of July.

Last year in Pittsburgh it was July before any showed up. Kind of late for them. Do fireflies hibernate?

At least July if not the warm days of early August here in QC. It has to be warm and humid.
