Until about a fifth of my life ago, I thought these black & yellow bugs were gigantic dangerous wasps. Then I found out they are placid hoverflies, wasp-mimics, mimicking for their own safety.

I've come to like them.

And that flower . . . I used to call them "blue daisies" and eventually, because "daisy" was apparently ambiguous, "blue asters."

Around the same time as my hoverfly epiphany, I realised people more widely called them Michaelmas asters, and so I followed.

Now I understand the DNA-botanists have shaken up the barrel containing all the asters, and I no longer know what to call them. I'm going back to blue daisies.

And I'm sticking with hoverfly.
