This is interesting to me ; I am a regular cyclist and I commented recently on the fact that when I was a kid, there were always 'clouds' of gnats in the evenings that typically swarmed around and you would bike through them... I havent encountered a swarm of little gnat in a very long time. However, I blame this on glyphosate which decimated the insect environments. The other thing, in the early 1980s in Lake Tahoe, there was a grove of trees near my elementary school where the Monarch Butterflies would congregate and an entire pine tree would be completely blanketed in them - havent seen that in decades. Milkweed is their only food and egg-laying spot (on the underside of the leaves) - but milkweed has been eradicated with glyphosate and thus no more Monarchs.
