I actually was sitting outside a few nights ago and realized that there was no more fireflies, and I couldn't remember the last time I had seen one. I used to go out all the time during summer as a kid to catch them, they would light up whole fields. That was just like 15 years ago. Pretty sobering realization
For me it's red wasps. Growing up in Texas there used to be so many, you could see them flying low searching for spiders in the grass. Last Sunday, in the heart of summer, I couldn't find a single red wasp where there used to be hundreds.
The lot is between the river and our local garden district. I suspect I'm part of a migration route between them (I figured I was too far from the river for dragonflies, but I see at least 2 a day) It's changing my plans for the space a bit.
