solitary Cicada killers live in a hole in the ground they dig themselves. They are gentle GIANTS. They will never harm a human.
They will scare you by flying close but that is it. They fight among themselves over territory.

What has killed 90% of all our American bees are the niconoid systemic pesticides and herbicides. France banned them all. The US will kill our bee for another 4 years before they phase them out due to poison company profit motives and legislation.

We have to truck bees to fields to pollinate farms. It is a very dire situation that can not wait for a better solution.
