Bronze fennel

I have some large unruly bronze fennel plants in my garden, which I was considering trimming.

That was until I discovered five black swallowtail caterpillars on it, and honey bees nectaring on the flowers.

There were also many other critters including this - black wasp?

Since you asked, are all female tiger swallowtail butterflies black?

No, many of the female tiger swallowtail butterflies are yellow.  In fact, if you live in an area that does not have pipevine swallowtails all the females are yellow.
