You're right JD. Haven't seen "lightning bugs" in several years now. Until just recently we haven't seen scorpions or red harvest ants but now they're starting to make a comeback in spite of me killing every one I see. What about horned toads? I haven't seen one of them in forty years. I used to play with them when I was a kid. Tied match boxes to their horns and let them pull the boxes like a train. Red wasps and yellow jackets seem to be thriving though as well as them cotton picking dirt daubers.
I've seen similar things here. I'm not a scientist, and don't have any evidence to back it up, but I believe that the decline of the things you listed, along with others (seed ticks come to mind), is related to fire ants coming in. The wasps haven't declined because they aren't on the ground where the ants could easily get to them. To reinforce that theory, I've noticed that the fire ants have declined in recent years, and that seems to correspond with the others making a recovery, as you mentioned.
Although they aren't anywhere as numerous as when I was a boy, I've definitely seen more lightning bugs the last few years. For a long time I rarely saw any.
