There's an official event in Appalachia next month; the bugs are synchronized. They just are I don't make the rules.

@b4cks4w I've heard of that happening, but I've never had the chance to see it. It must be an amazing sight!
@HaikuHedgehog Fireflies start to appear in the US when temperatures are consistently above 65°F (18°C). For most of the US, that typically happens in late spring or early summer. Fireflies can be seen in abundance as late as September in some places.
