Where Have the Fire Flies Gone?

I see lots of fireflies, they just have a short gestation period. About two or three weeks, that's all they're out for. Usually between June and July. Most insects are only spawning for a short period. Dragon Flies are no different. First comes the Horse Flies and House flies around Mayday and they peak around Memorial Day, and then the Dragon Flies come out and gobble up lots of them from July into August, that lasts about two months. The Mayflies are also usually only out around August and September--ironically because they're called "mayfly" but aren't out very long. Ticks also come out for a short period, about two months. I've observed that for close to seven years now. The Fire Flies aren't out for very long, and most people just aren't outdoors during the summer anymore, so they miss them. Now House Flies have a long gestation period, and so do Mosquitoes. But horseflies are usually dormant in Late August or Early September.
