I'm not quite as 'mature' as you but grew up catching them in SW Houston. They were around in Spring TX while I was there from '92 - '05 but not nearly as thick as my childhood. I don't recall the last time I saw one here until moments ago, a single lightning bug. Flashed about 10 times then suddenly disappeared . . it may have got sucked into the neighbors AC. lolAnother thing I haven't seen in years in the Houston area is fireflies.
Here in rural Arkansas they are now out every night by the lake.
Brings back memories just seeing them.
