You could have something there though..?
But, it would have to be some tough m...... insect, cause butterflies, bumbles, hummingbirds, etc, are also disappearing - although they don't get as much "airtime" as bees do. And they all have one thing in common - they feed on flowers?
Now, bats are/were dying all winter and apparently they didn't feed enough/too much on insects which in turn fed on. . .
Well, it just seems to go around and around?
