Scary stuff.
If it were the poles reversing, wouldn’t it be affecting other somewhat-related insect species as well, such as wasps? I’ve sure not noticed any lack of wasps over recent years. I thought than I had heard speculation about the cause being something far less exotic than reversing polarity, like disease or a parasite. G's link would indicate that these and related theories are the main ones.
When there's an eel in the lake that's as long as a snake that's a moray.
